[quote user="paulaE"]I just installed Pegasus Mail v4.62 for Windows 2000/XP/Vista/Win7 (Nov. 3, 2011)
And immediately needed to uninstall it.[/quote]
No need to panic, would you mind to tell us why?
[quote user="paulaE"]I went to the "Control panel/Add or Remove Programs", where there were 2 entries, one for pegasus mail and one titled "Pegasus Mail HTML Renderer 2.4.5.18"; I clicked to remove the email program and it was removed.
Then, in control panel, I clicked to remove "Pegasus Mail HTML Renderer 2.4.5.18" and I received an error window: "Cannot find WINPM-32.EXE - setup aborted!".
I used the windows search program to search for WINPM-32.EXE (including system and hidden files and folders. It doesn't appear to be on my hard drive.[/quote]
Certainly, you already removed this file (Pegasus Mail's main executable) with the previous uninstall command. Doing it the other way round would have avoided this.
[quote user="paulaE"]But the entry "Pegasus Mail HTML Renderer 2.4.5.18" remains in my control panel.[/quote]
Does the directory you installed Pegasus Mail to still exist (typically C:\PMAIL)? If so you may want to remove it including all remaining contents which might include any emails retrieved with Pegasus Mail, but it'll certainly removed IERenderer as well - but not the Registry entry responsible for displaying in your Control Panel view. For doing so you need to remove the Registry key HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\{A9F5E1E1-1281-4862-90B4-6CF8E6AF83CE}_is1 (depending on the Windows version you use you may need to omit the "Wow6432Node" section which only exists on 64-bit Windows). Be extremely careful with modifying the Registry, though, it may completely hose your system if doing something wrong: It might be a good idea to create a system restore point before trying - unless you're experienced enough to know what you're doing.
[quote user="paulaE"]I also tried a a hard drive search (files and folders) for "pmail" and found
C:\WINDOWS\Prefetch\PMAILW32-462.EXE-0C6F15B1.pf (dated today) and wonder if I should delete that file.
In fact, in that windows directory there are a bunch of files, dated today, that seem suggestive of Pmail, such as
SETPMDEFAULT.EXE-0BEA97E4.pf
IERENDERER.TMP-2F415623.pf
IERENDERER.EXE-1C82BC9E.pf
Should any of these be deleted?[/quote]
These are so-called "prefetch" files which allow Window to launch frequently used applications faster, they are maintained by Windows and I don't know whether outdated ones will be removed automatically or not, doing an Internet search would probably reveal it.
