when trying to open photo's, a message box says,... jpg is not a valid win 32 application.. why does this happen and how can i fix it to open my photo's please?

How exactly are you trying to open these images, and with what program?

Go to any picture file. Right click on it. Go to Properties on the drop down menu that appears. Tell us what appears under "opens with."

I am trying to open with PhotoStudio 2000.

Doing the above, it says under "opens with" - Microsoft Photo Editor!

My pictures won't open with PhotoStudio, only with Microsoft Photo Editor.

When I try using PhotoStudio I am told "jpg is not a valid Win 32 Application".

Even though I have gone to "properties" and changed "opens with" Microsoft Photo Editor to "opens with" PhotoStudio" !!!

When using Windows Explorer, if you double-click on a jpg file, does it now open and in what program?

Yes it DOES open, but in Microsoft Photo Editor !

I have merged the other topic you started, with this one.
Please keep all responses, confined to this topic.
Starting two topics, about the same problem, is called Double Posting, and is not allowed on this board.

My apologies for doubling. I won't do it again.

I have been to Computer/Tools/Folder Options/File Tabs/selected jpeg/change/Open with/and chose PhotoStudio 2000/OK.

But when I try to open a jpeg file it still goes to the message "jpg is not a valid Win 32 Application" !!!!!!!!!!!

And if I look at any one of my jpeg file's properties, it does say that it opens with PhotoStudio 2000 !!!!!!!!!!!!!!!!!

PhotoStudio 2000 may have become corrupt.
Have you tried reinstalling it?

It could have also been infected with a virus.
Have you updated, and run, your Antivirus?

Have re-installed but no change.

My anti-virus runs continually - so no virus.
