KB: Windows error message “Vptray.exe fails to initialize” and/or “ccApp fails to initialize” after Zoom
KB#: 134
Last updated: November 21 2006
The information in this article applies to:
- ZoomText 8.1x
- ZoomText 9.00.x - 9.01.x
- Non-Admin accounts on NTFS file system
PROBLEM
After installing ZoomText, the following Windows errors occur when starting ZoomText:
"Vptray.exe failed to initialize"
and/or
"ccApp failed to initialize"
These errors may also occur when launching other programs, such as Norton and Symantec antivirus programs.
CAUSE
This problem occurs because the ZoomText Setup program has incorrectly changed the user permissions for the MFC71.dll and MSVCR71.dll files. These files are used by ZoomText and other programs, and must have the appropriate user permissions to operate properly.
Note: This problem is limited to computers with NTFS files systems and in any non-admin Windows account (for example, Power User or Limited User).
WORKAROUND
Log in as an administrator and give all users permissions to these files:
- MFC71.dll
- MSVCR71.dll
One way to change the permissions is to type these two lines at the command prompt:
- cacls %WINDIR%\SYSTEM32/mfc71.dll /E /G Everyone:F
- cacls %WINDIR%\SYSTEM32/msvcr71.dll /E /G Everyone:F
Note: This problem is fixed in ZoomText 9.02.
