UnRar.dll error when updating Build OS

[sigmanuelder]

Hey guys,

I am hoping someone can help me out.

I keep getting a "Can't copy file" error when updating the BuildOS application.

It says that it can't copy file UnRAR.dll and then under more details it says "There can be several reasons for this error. The file is not available or the file is in use by another application."

Any ideas?

Thanks, Sigmanuelder
