RSwho Problems RSLinx 3.90 Free Version

I am unable to view RSwho on the free version of RSlinx V3.90. The message I get is, "failed to show RSWho. Cant access file: C:\ProgramFiles(X86)\RockwellSoftware\RSCommon\Harmony.rsh". I have tried deleting the Harmony file from rscommon, uninstalling/reinstalling multiple times, etc. When I deleted the Harmony file and tried to open it, it said, "Failed to show RSWho. There are some unknown reasons, such as: Out of memory. No enough disk space...etc." When I reinstalled RSLinx and tried running it with administrator, I received no notifications. RSWho just wouldnt work. This is a newly purchased computer (Lenovo W530) with 24gb ram and a 500gb SSD. I have windows 10 pro but im sure its an upgrade. If anyone could help that be awesome!!

This may help, see links

This is good information, thank you. I am suspecting something with windows being the issue, so I am glad you gave me a solid direction including update numbers. I will try this tonight after work and let you know if it works!

That was it!! Thanks, you saved me a ton of more frustration! This was also messing up my other software installs.

You're welcome. You are not alone, several others have posted about this lately.

I seen that. Hopefully the folks at Windows are aware and get that fixed asap!
