I purchased sudoku on 7/2/2005, installed it, entered the key and name, and the program functioned as advertised.
This morning, 7/7/2005, it gave me an error message that "sudo.exe" was missing and gave an old-fashioned Windows 3 pathname. Despite that, I managed to find the directory it was referring to and verified that indeed, sudo.exe was not there. There was a sudo.exe.manifest file. Changing its name to sudo.exe did not solve the problem.
I uninstalled sudoku and deleted the appropriate references to it in the registry in case there was spurious information there about a trial period. I redownloaded the software and attempted to install it. The process aborted. It complained that the source file "sudo.exe" was missing from the same screwy path name.
I have Kaspersky Antivirus. My understanding is that it deleted sudo.exe this morning because it (sudo.exe) allegedly or inadvertently delivers a virus of some sort, or behaves as if it does.
Can you deliver a functioning, virus-free version of this product? If not, you must issue refunds. How do I get my money back?
