I love ACDSee ...but...upon trying out the latest trial version...which loaded peacably the first time...and subsequently got lost on a reformat [due to my frustration with XP], it absolutely refused to load past the point of file associations, jpg being the first and last instance.
As in like cases, in the past, I have had to remove all of XP-SP2 and its updates, install the program to be tested, and then re-install XP-SP2, etc.. Slip it in under the sheets, so to speak. Thankfully, I have the disk and the time to do it. As a beta-tester, I am used to following this routine, and have back-ups, up the yin yang for everything.
Now, ACDSee is not the only program that is affected by XP-SP2...there are many others, and the same resolute stubborness occurs each time...me against the hard-drive. A re-install is the only solution.
XP is, jealously, the most proprietory of all versions of Windows. It does not like other programs in its immediate vicinity...like on the hard-drive! All 3rd party software is suspect and there for met with resistance. Like all MS products [don'tchu just love them?] they make aggrevating bedfellows with 3rd party stuff. You, almost, have to beat it into submission, and threaten it with a reformat...mess with its head!
Partitioning the hard-drive then becomes an unattractive option...but...non-MS files have to be filed in the system32 folder, if you are not 100% operating in the particular drive where the prog was installed...ie. you have to run XP-SP1 in the active partition, ie. where you are working, and XP-SP2 in the native partition, or logical partition. Have I got that right? Anyway, I think that you get my drift. Two OS's, to use some non-MS software, in some cases.
Now, doesn't that sound stupid
