Nah .. Install.log contains the installation log of the program .. It is created by the installer for removing the program . .When it isnt find where are you gonna locate it ..? If you use another program's install log the program that you intend to remove wont be gone ..
The error comes when the install program dont find the file on the expected location .. There is nothing you can do it ..

Another solution can be to run the setup again and install the program all over it .. So a new copy of install.log will be created in the program directory ..
