BleepingComputer.com: Error when trying to update adobe

I am trying to update Adobe Reader and I get the following error:
Error 1402.Could not open key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run\OptionalComponents\MSFS. Verify that you have sufficient access to that key, or contact your support personnel.

I have recently had help in the malware section of this website to remove malware from my computer. I am worried that something may have gotten deleted that should not have. I encountered this error when tryin to update Adobe Reader to the most recent version for better security.

Here is the thread from where I got help with the malware.

I appreciate any help.

Adobe always has been a PITA
I would ditch it entirely and try Foxit. Much less bloated
