Runtime error 13 in application I am using

Hi - I am not a programmer and am not posting about an error in my own code. I have a handheld ham radio that comes with a couple pieces of software - one for updating firmware on the radio and one for programming the radio. Both recently started failing to launch with Run-time error '13': Type mismatch. I do not recall if this started after a specific Windows update or after installing any other software.

I have tried uninstalling the software, deleting all old files and directories, and re-installing. I have tried installing older versions and newer ones. I have searched the registry for related keys, unsuccessfully.

Right now I can't upgrade my radio nor edit the configuration.

Are there suggestions for solving this that I haven't tried? I am reasonably computer savvy and don't mind working int the registry or clearing out files and directories. If it could be solved by downloading and installing updates to VB I could certainly handle that.

Thanks for any suggestions.
