Step 2.4. Rollbacks

Sometimes the Parallels Tools installation stops in the middle of the process and then rolls back without an error message. Parallels Tools installation wizard may just warn you that installation failed and reboot is needed. In such cases it is necessary to investigate parallels-tools-setup-xxx.log file that is located in C:\WINDOWS\Temp folder.

Go to the end of file. Make sure that the last string contains actual date & time from Windows:

    "=== Verbose logging stopped: 7/4/2011 14:13:04 ==="

Return code 3010 in one of the previous strings means OK. Parallels Tools was installed successfully.

    "MainEngineThread is returning 3010" 

Return code 1603 means 'failed'. Note, that message "Info 1603" is not the error itself!

Search for the beginning of the current log. Scroll up to the previous "Verbose logging started" occurence. Be sure that date & time of beginning of the log are actual.

    "=== Verbose logging started: 10/28/2010 15:38:10 Build type: SHIP UNICODE 5.00.7600.00 Calling process: C:\Windows\SysWOW64\msiexec.exe ==="

Search for the first occurence of "Rollback:" message as first symbol in the string. Look up error code in some strings above this "Rollback:"

Error 1627:

Look for the following strings:

    DIFXAPP: ERROR: InstallDriverPackages failed with error 0x65B 
    DIFXAPP: RETURN: InstallDriverPackages() 1627 (0x65B)

Delete the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\FileScreenFilter.

Error code 0xE0000100:

    Error code 0xE0000100: The style of the INF is different than what was requested

Error code 0x3

    Error code 0x3: The system cannot find the path specified Could not open file
    (Error code 0x3: The system cannot find the path specified.)

Step 2.5. Submit Problem Report:

If the issue is still not solved or you have difficulties with any of the steps outlined above, please submit the Problem Report from Help menu > Report a Problem.

Remember the Problem Report ID and keep it for technical support department.
