I have commented notes into the code in places, keep in mind it was still a very rough throw together job. Some other thinks I noted also were once the installer detected any previous botched installs (which it does pretty well) and it removes it, the FileDelete and DirRemove functions only worked approximately half the time or sometimes less. FileDelete on the directory level removed the files inside the directory but not the directory it's self...which is not surprising, but DirRemove should delete the whole directory and it doesn't do sh!t? Occassionally I would do FileDelete then DirRemove and it would work....but not always, so good ol command prompt del /Q command always works a treat

That being said don't be at all surprised at my "hack" like code lol

I only do what has worked on my Windows 7 x64 ultimate machine.
I've looked at your code, and am basically writing a gui for it, cleaning code, and moving things like cleaning old installs, uninstalling, installing, etc to their own functions.
As for the name, users will be able to install it for multiple file types. This means they could have it only open .png and .jpg files, and I fear with a title like "Windows 7 Gif viewer" would appear silly if it doesn't open gifs
A lot of the people using this are people who also used XP, and considering that "Windows (XP's) Picture and Fax Viewer"
is what it is it feels a little dishonest to call it anything else. Mind that, the name is a little long an ambiguous. maybe something like "Windows Picture and Gif Viewer" Is more appropriate? (similar wording to original, includes keyword Gif, doesn't imply Gif-exclusivity)
You can take a look at what I work out and see if you like it. I'll upload later today
EDIT: forgot why i quoted that bit. Looking at the autoit forum, filedelete and dirremove are designed not to delete files with the system attribute, as a sort of safety mesure. I've updated the code to account for this, so hopefully we won't need the dos bits. I'm working on some of the code at work, and some at home... so I can't update git quite yet. Check your Gmail
@corgano & Jarmezrocks, there are at 4 different threads pertaining to 'gif viewer, XP Pic Viewer, etc., & I guess I picked the wrong one to post my question to. I posted in "animated gifs and windows photo viewer" about 2 weeks ago. Could you possibly look at my question there & give me a reply, please?
Thank you.
Not sure what you were taking about though to be honest
