There was one CCleaner process running in Task Manager. I ended it and tried to install v.5 but I got the same error messages:
If I select "open" to run the v.5 download, it freezes and nothing happens.
If I select "save" then double tap on the saved file (ccsetup500_exe), I get the "How do you want to open this file?" message with Internet Shortcut Shell Extension DLL program recommended. When I select that, nothing happens.
Yes, I have version 4.19 installed. Since you told me where I can go to re-install that version, I removed it from the tablet and tried to install v.5 from the saved downloaded file but still got the same error messages.
I noticed, however, that the downloaded v.5 file was named "ccsetup500_exe" with no period (".") included in the name so, on a flier, I changed the file name to "ccsetup500.exe" (changed the underscore "_" to a period ".") and tried it. Didn't get any error messages and it installed like a charm.
Why in the world would they give you a version application file to download and have it be unusable since it is named incorrectly????
The wonderful world of computers!!
