Google drive error : python27.dll

May be a problem related to permissions (look for System Error Codes). Try the following.

1. Open the Windows Explorer.
2. Paste this(%UserProfile%\AppData\Local\) in address bar.
3. Right click on folder Temp then Properties - Security tab - Advanced button.
4. Click on button Change Permissions.
5. Remove all permissions.
6. Select the entry for your user name and click Edit.
   • Include inheritable permissions from this object's parent.
   • Replace all child object permissions with inheritable permissions from this object.
7. Click OK.

One fix is to set GoogleDriveSync.exe (generally located in : C:\Program Files\Google\Drive) in compatibility mode :

• Right-click on the executable -> Properties -> Compatiblity -> Run this program in compatibility mode for : Windows 7 (I assume you're running Windows 8, otherwise try setting an older OS version)

For windows 8 system, follow the steps bellow:

1. Open the Windows Explorer.
2. Paste this(%UserProfile%\AppData\Local) in address bar.
3. Right click on folder Temp then Properties - Security tab - Advanced button.
4. Click in Everyone, Mark Change Permission and later click Edit
5. Mark all permissions
6. Press Ok (continue) in all windows questions.
