[amsat-bb] SATPC32 Error Code 1925

On two of my windows 7 computers I have not been able to install SatPC32 because I get the error message that I do not have administrator privileges. I only have one account on these machines and it is an administrator account. On other machines I do not get this error message. Do you know what causes this error and how to work around it? I have been told to right click on the setup.exe file an run as an administrator, but that option does not appear on my computer. Using latest version of SATPC32.

Thanks,
