“Could not Open Install.Log File!” Problem Solved!!

You may have noticed a problem when uninstalling some programs, if you have Ntfs in Windows XP, Vista or 7, you are likely to face this problem. When you try to uninstall ’em from Add/Remove Programs List, they show a message “Could not Open Install.Log File!”. This problem is generally seen with “Wise Installation Wizard”. I have seen it only with “Wise Installation Wizard”. I don’t know if other installers give rise to same problem.

When you try to uninstall them from
Start Menu>>Programs>>%ProgramName%>>Uninstall
It again gives the same error.

This can be solved and the program can be un-installed without having to remove the directory, shortcuts and registry entries manually, which is really difficult and tiresome. I have found a solution to this problem and sharing with you all.

1. Open the directory where the program is installed. (Eg. For System Mechanic 5, By default, it is C:\Program Files\iolo\System Mechanic 5, if you have installed XP on C:\)
2. You will see a file named “Install.log” in there.
3. Move (cut and paste somewhere else) the “install.log” to say an empty new folder in desktop (first create a new folder and then paste the install.log into it).
4. Now, double click the un-installer (uninstall.exe or unwise.exe)
5. It will ask you to open the installation log. Locate to the “install.log” file on your desktop.
6. Now, uninstall will work fine and you can un-install the program.

Alternate Procedure
You can simply drag the install.log to unwise.exe or uninstall.exe and it should work.

This should solve your problem and the program should be uninstalled.

      Atem – That worked, when every other way listed above failed! Moving the UNINSTALL.EXE to the Desktop instead of the INSTALL.LOG file. Moving the INSTALL.LOG file did not work for me, it never prompted for the location but still said “Can’t open INSTALL.LOG file”. But moving the UNINSTALL.EXE to the Desktop and running that, worked perfectly. Thanks!

    I’ve had heaps of issues trying to remove SmartDraw from my computer, your instructions, that i ‘found’ online were the only ones that worked!!!

  • Alek2tl

    • Apzaza8

      i had this problem too until well…the simple solution is to go to C driver–> program files–> and to just delete the program file,after when you go to start–>control panel–> add or remove program, to uninstall the program it will be much easier :))

    THANK YOU THANK YOU THANK YOU!!! I’ve been trying to get rid of an annoying Amazing Photo Editor program forever and this worked

  • Guest

    Wrong mate. The correct syntax is “C:Program FilesUNWISE.EXE” /Z/S “C:Program FilesINSTALL.LOG”

    This will run the uninstall in automatic/silent mode. Cheers.

  • medomedo

  • Mato

    I love you!!! 😀 thx alot! I´l never install Rhino crap again

  • littlewings

    Worked for me perfectly, thanks!!!!!!!!

  • Bill Smith

    I’m kinda old fashioned, when a program gives me trouble like that I go the trusty C: prompt and delete it in its own Directory.

  • rod

    that worked thank you

  • your procedure works, becareful to avoid hack solutions like Apzaza8 is advocating because all sorts of framgents files will be left everywhere. This is a perfect solution to the install log not being read….I have no reason why the file is not read….but this original solution works.

  • Raj
