Google Earth Pro
7.3.1.4507 (64-bit)
But, can i install 32bit software in a 64bit computer?

Sure, but your AcadVer but an exactly version-type with GoogleEarth.
//Eg1. Autocad2014.exe version x86 and GoogleEarth.x86
//Eg2. Autocad2014,exe version x64 == GoogleEarth.x64
Other solution/s check>your WindowsRegistry with
"Spy Search and Destroy.exe"
"Windoc.exe from NortonUtitiles", because "winRegistry for 'COM" contain damage-informations.
"Check the virus Attack with BitDefender.exe":
