I am trying to download software. It stalls about 60 percent through and I get a pop up box with this message:
Error 1720. There is a problem with this Windows Installer package. A script required for this install to complete could not be run. Contact your support personnel or package vendor.
I am running windows 8.1 with IE 11. My work wants me to run IE 8 or 9 because they are slow getting updated. I have changed my internet all around and have had success running other programs for my work. I have been told that I am getting this error message because I have a virus. I have run Avast and Malware bytes and they both come up clean. I went to Microsoft.com and ran a diagnostic fix it tool to fix my registry. The program said that I did not have any problems with my registry and it did not fix anything. I tried to do system restore and roll my system back to an earlier date so see if that might help. I am unable to do do system restore. When I reboot my computer a pop box appears that says system restore failed would you like to try again. Now my internet options are all messed up and I am unable to run any work applications.
I think I can fix the internet options but I still have the Error 1720 code that I do not know about.
