Perhaps you are using CCleaner for nothing. Often it harms the system worse than a virus.
I can assume that something is wrong with the access rights to the folder in which the program is installed.
It would be good to completely delete all the program folders before installing again.
Look at her folders in the following places:
Program Files, Program Files86, ProgramData, C:\Users\User name\AppData\Local, C:\Users\User name\AppData\LocalLow, C:\Users\User name\AppData\Roaming.
In the registry, look for the branch from the program in the following place:
HKEY_CURRENT_USER\Software
Probably these are not all the places where the program files are located, but it may be enough for a successful reinstallation.
It is also necessary to check the folder that is specified in the error message.
It would be nice to know which files were deleted when cleaning from malware. Maybe there were dependencies.
System files may be corrupted after infection.

P.s. I have been a lover of astronomy since childhood. Space is my home. But I have not used such programs.
