Contacts Sync Pro v3 - Help

Error: Can't fetch Gmail Contacts. Check Network Connection" and in Log you see Cant Fetch Groups. Execution of request failed:

Solution: Signin Manually. Here is how: This is an onetime task, no need to do each time.

In Contacts Sync, click "Signin to Google" button When browser window pops-up, at the bottom of the window- click the button "Manual Signin using default Browser"

If the windows does not popup, edit the gmail username/password boxes in Contacts Sync - just type a wrong password and click "Save Settings"

After you click "Manual Signin using default Browser" button, your default browser opens, then sign-in to the right google account and then you will see a long code. Copy the code.

Come back to Contacts Sync, go to "Configuration 2" tab. Paste code in the box provided (Paste Code here box) and click Sign-in.

Then in Contacts Sync, type the correct password (necessary only if you have modified your password in the above step)and Save Settings.

And do Sync. It will work fine.

Due to changes in Google authentication method (OAuth1 to OAuth2) , older Contacts Sync Pro versions (1.x/2.x) will stop working on/after April 20th, 2015.
Please download Pro version 3 and use to avoid disruption.

What's new in Contacts Sync Pro v3: (windows version)

- One-time sign-in browser window will popup to sign-in to your Google account. There will an one-time sign-in prompt asking for user's consent. You will be only authorizing the Contacts Sync app installed on your computer to access your contacts.
- Optional Sign-in button (see below on when you must use this)
- "Configuration 2" tab has Google OAuth Login (to use your own Google OAuth code (Optional)) and Paste code box for Manual sign-in.
- "Profile 2" Gmail settings moved to new tab "Profile 2 Config" - 2nd Profile and Sync both Profiles option will not work.

1. Issues: Trouble signing-in ? Browser window is blank or Browser showing javascript error ?

- If you have trouble with sign-in, click on button "Manual Sign-in using default Web browser" seen at the bottom of popup sign-in window.
This opens the Google sign-in in your default web browser.
Complete the Google sign-in and give your consent by clicking "Access" button. You will then see a code.
Copy this code.
Go to Contacts Sync Pro-->Configuration 2-->Manual Sign-in option.
Paste the code in the box provided and click Sign-in and wait for a few seconds. You will see "Signed-in as: <your Gmail email>". You are now set to do the sync.
This is just an one-time task. No need to do these steps again.

2. Google Sign-in screen keeps flashing with password error or Unable to type anything in Google sign-in screen that pops-up after clicking on "Sign-in to Google" or Synchronize button.

You will not be able to enter anything in the Google sign-in popup window. You need to first enter Gmail username/password only in Contacts Sync Pro software. Then click "Save Settings". This saved information will be used for automatic sign-in and you don't need to do anything after your click Sign-In or Synchronize.

3. Application specific password (App Passwords) will not work.

Contacts Sync Pro v3 uses the OAuth2 authentication method recommended by Google and so if you have been using "Application specific password" (App Password) in Contacts Sync, it will no longer work. You need to just sign-in one-time with your Gmail account password and the 2-Step verification code.

4. Sign-in to Google button

You must click this Sign-in button when you change your Gmail account in Contacts Sync or use new password.

Other Issues

1.Error: "Unable to find a version of the runtime to run this application"

This can happen if you have .NET Framwork 4.0 without the older versions of the .NET framework. Download and install .NET Framework 3.5 to fix this problem. If that does not fix, seach in Google for possible solutions or email us.

2. Error: "Check username and password.. Invalid Credentials"

Solution: If you are sure you have entered your Gmail username and password correctly, then after entering/modifying Gmail username and password, make sure you click "Save Settings" button. Contacts Sync first needs to store your Gmail settings before starting the sync. If 2-step verification is turned on in your Google Account settings, do not use the password that you get by voice/text message, you must create a application specific password and use that in Contacts Sync. Learn more about this from Google. Or Enable "Access for less secure apps" in Google Account settings.

3. Contacts Sync transfers Outlook contacts to Gmail's "Other Contacts" but the contacts are not seen in Android phone.

Option 1: Upgrade to Contacts Sync Pro version. If you prefer to use Free version, you can easily do a one-time task of moving all contacts in Gmail to "My Contacts" from the Gmail Contacts screen. Alternately change Contacts display settings in your Phone to include Gmail's Other Contacts group..

You need to modify the Display settings in Android phone inorder to view all contact groups from Gmail. Here is how:
Navigate to Contacts and then go to Menu -> Display Options. Here you can select each account and also select the Groups that you want in your contacts in Gmail to show up on your Android Contacts list. Typically tick "All other Contacts". You may also need to modify "Accounts & Sync" settings to sync the right contact group in your Android phone.

4. Error: Invalid Credentials and a message popup "-24147,12"

Contacts Sync is unable to decrypt the password you have entered. This has been fixed in Contacts Sync v3.1. Try this Workaround: Use 2-step verification for your Gmail account and create application specific password and then copy the password generated by Google and paste into Contacts Sync password box. Save Settings and try sync again. If this workaround doesn't work, use a newer version of Contacts Sync Free or Pro.

5. Selecting a Outlook Contacts Folder: The pull down menu extends beyond the right side of the available window. This hides the down arrow of the pull down menu.

This can happen when the name of your Outlook Contacts folder is very long. Just click on the pull down menu and press the down/up arrow key and you should be able to select the folder. Or try to rename the outlook contacts folder which has a long name and then click Load Default Folder again and now you should be able to see the down-arrow of the pull down menu and you can now choose the folder using your mouse.

6. Error: Interface not registered (Exception from HRESULT: 0x80040155).

Error is related to a corrupt MS-Outlook/MS-Office component. Try MS-Outlook/MS-Office Repair Try the following:-
Outlook automatic diagnose and repair: In Outlook 2007, there is an option is to run Office Diagnostics. This built-in tool runs a series of tests and repairs many common Outlook program errors. To use this tool, simply go to:

7. Outlook Security Warning: A program is trying to access e-mail address information stored in Outlook.. .... Allow/Deny access...

Under certain conditions, installing an antivirus program and keeping it updated regularly might prevent this security warning from appearing again. The conditions are as follows:
1. Your antivirus software must be updated regularly.
2. "Windows Security Center" in your PC should be configured to identify your antivirus software and should report its status as ON. Outlook first checks for the current status of antivirus software by querying the Windows Security Center.
3. Open Outlook Trust Center, open the Tools menu and then to Options and click Trust Center. In the Trust Center, click Programmatic Access. The following option is set:
"Warn me about suspicious activity when my antivirus software is inactive or out-of-date (recommended)"

* Outlook relies on the Windows Security Center to check for the presence of the antivirus software and update its status.
* If your antivirus software subscription expires or is inactive, you might get the security warning again when a program tries to access Outlook.

8. Error message in Log: Your server administrator has limited the number of items you can open simultaneously. Try closing messages you have opened or removing attachments and images from unsent messages you are composing.

You will get this when you are connected to MS-Exchange server and when your Outlook connections are limited due to policy. Contact us to get an upgrade to fix this issue.


9. Unable to see Outlook Contacts Folders in Contacts Sync ? You might see the following error in the Log when you click on "Load Default Folders" or Browse Folder.

Error Fetching Folder : Unable to cast COM object of type 'System.__ComObject' to interface type 'Microsoft.Office.Interop.Outlook.NameSpace'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{00063002-0000-0000-C000-000000000046}' failed
due to the following error: Error loading type library/DLL. (Exception from HRESULT: 0x80029C4A (TYPE_E_CANTLOADLIBRARY)).

This can happen if you are using 64 bit OS and 32 bit MS-Office / Outlook. This does not happen for everyone. If you do see this error, then download the 32 bit version of Contacts Sync Free v4.5. If you are using Lite or Pro, please email us to get this 32 bit-only version.
