Introduction When Installing Adwords Editor on my Windows Vista Laptop I keep getting Error code 2739 and searching the Net also did not help and I managed to find something where people had same problem for some Photo software from Google and applying the same solved my problem and so thought would write more about it so that it would help. The Steps Open Command Prompt in Admin more by Right Clicking on it and choosing Run As Administrator ( You may need to confirm as well as enter password depending on your Admin account settings ) Change the Directory to your System32 Drive. In my case it is C:\Windows\System32 . Now you command prompt reads as C:\Windows\System32> Now Execute the following 2 command regsvr32 vbscript.dll regsvr32 jscript.dll Now start installation of Adwords Editor again and that would work perfectly fine. At least it does for me.
