I see the same problem on my system (Window 10).
My guess is a problem with the installation of the lightroom plugin.
I don't use Lightroom, but there might by some garbage from an old lightroom vesrion 1 from 10 yiear ago or so.
What might be the reason for this. I do not need the Lightroom-Plugin.

Thanks

P.S.: Since I allways keep copies of the pder versions, I reinstalled version qu24-100p.exe and this version works
and is installable with my personal account. ok, I am asked for the admin-account during the instalation process.
But that is how it worked for years.

I've now had time to look at the TIFF you sent (thanks for that!).

The EXIF header is corrupted.  The size of the EXIF header is 31 MB which is larger than the whole file.  I'm not sure whether it is an infinite loop inside the EXIF data or some other problem but the EXIF reader that I use is able to handle the corruption but the EXIF writer that is used when a new copy is saved crashes.  Not much I can do as it's a third party add-on and not my code... nor would I spend much time on it since it is not the fault of Qimage.

The software used to save that TIFF is listed as "paint.net 5.0.13".  Not quite sure what that is but I would venture a guess that it's a bug in that software since that is what saved the TIFF.  Maybe just avoid that tool for the final save?

If you are having to log in as admin, it sounds like you ran the installer as admin and you are now using a limited account to actually use Qimage.  Did you try the method I suggested: running the installer again under your own user account?

I used to have a 24" Epson 7890 and wore it out over the years. I have replaced it with the P900 which prints A2, if I need bigger, which is rare, I get someone else to do it. My point being that I love the P900. I was worried going from 320mm carts down to 50mm but it is no problem. I have had the printer about a year now and have never had to do a head clean. The space the 7890 was in is now an excecise bike :-) > go for it. Get the P900, you won't regret it.

Thanks for your help Mike. It seems the only way I can now run it is by R/clicking and choosing Run as Administrator, then having to log I as Admin with password etc. I didn't ever (in the last eleven years :-) of using have to do this. Do you know how I could change it back to running from a click on the Icon?

Try running the installer again and make sure to run it under your user account: the one you intend to use for Qimage Ultimate.  Most problems like this are caused by running the installer under admin and then switching to another user account when you actually want to use Qimage.  That's the only way you can end up with no access to your own user files.

Looking at your image, I tried to find that location on my computer and could not.

Though I did find ddisoftware at

C:\ProgramData\ddisoftware\Qimage

Hi. I have been running Qimage forage and love it and rely on it. Yesterday I downloaded a new update. But now I cannot run the programme and have a stream of printing to do. I have added a screen shot of the problem and have never had this before. I have tried to go to folders and I think I have permissions. but am stumped as to what to do. Can you help?

Many thanks... I have sent you an email. 

Thanks Mike
