DMdoc Posted July 28, 2014 Share Posted July 28, 2014 (edited) When I click on "Print" a Windows warning box pops up: "paint.net The Windows Image Acquisition (WIA) library, "wiaaut.dll" is unavailable. Please read the Help file... for troubleshooting information. OK" This only occurs on one of my computers, a Dell desktop running Windows 7 Home Edition. I tried uninstalling a version of Paint.net when it first showed up, and reinstalled from a fresh download, but still there. I found the dll on my harddisk and put a copy in the C:\Paint-dot-NET folder, but that didn't help either. The problem has been there in several versions of Paint.net, and I keep hoping the next version will resolve it. Any suggestions? Thanks! 29july2014: I've tried several ideas (listed in a comment below), to date unsuccessfully. I'm still open to further ideas...

sashwilko Posted July 28, 2014 Share Posted July 28, 2014 Hi. I don't think that "wiaaut.dll" belongs in your paint.net folder, I am almost sure it goes in to your Windows / system32 folder. I would not go messing around with things in there though without checking a windows help forum out. Link to comment Share on other sites More sharing options...
zeromus Posted July 28, 2014 Share Posted July 28, 2014 Sounds like most likely someone who didn't know what the 'windows image acquisition service' was for disabled it. Restore its setting to automatic, and it can solve this error message (which might should be rewritten to mention this possibility). It's also possible that your WIA is broken and every time the service tries to start, it fails. You might could detect this by manually starting the service and see if it fails. In that case your windows event viewer should contain some information about why its not functioning. Link to comment Share on other sites More sharing options...
Pixey Posted July 29, 2014 Share Posted July 29, 2014 (edited) Have you tried the 'Repair' in PDN? Go to your Paint.NET file folder and in there is a PdnRepair.exe file .... click on that. Also, sometimes uninstalling PDN can mess up the installation of another download. You can read all about it here. I realise it may not be a PDN problem, but it's worth a try.

DMdoc Posted July 29, 2014 Author Share Posted July 29, 2014 (edited) I appreciate the feedback; thanks. Here's what I've tried so far... 1) I had copied "wiaaut.dll" -- the original was still in my Windows / system32 folder. 2) WAIS was set on automatic. I restarted it just to be sure, and the issue persists 3) I tried PdnRepair.exe, no help. 4) I again uninstalled PDN (after checking that I had Microsoft net 4.5) and reinstalled from a fresh download of the PDN 4.0.3 version into a different folder in C:\ -- Issue still persists. 4) I also tried adding the files from Print It (Tools Effect) Further suggestions would be appreciated...... BTW, my workaround is to save files from PDN on the hard disk & open and print from Paint... cumbersome but it works.

nitenurse79 Posted July 29, 2014 Share Posted July 29, 2014 As Sasha has already mentioned the - wiaaut.dll - does not belong in the paint.net folder, it belongs in system32 for a reason, making copies of system .dll's or moving them around is not something I would be doing. If you still have the wiaaut.dll in the paint.net folder I suggest you remove it. You mention that you can print by using ms paint? Then it is clear that the wiaaut.dll you have copied to paint.net folder is the problem and is conflicting with the other one. Link to comment Share on other sites More sharing options...
zeromus Posted July 29, 2014 Share Posted July 29, 2014 mspaint doesnt seem to use WIA, so that isn't informative. maybe running a regsvr32 c:\windows\system32\wiaaut.dll would help. I'm not sure who installs wiaaut.dll, the internet seems kind of unclear on the subject. perhaps yours has been overwritten by another program. mine is 6.1.7600.16385 In your registry, you can check for this and make sure it's pointing at %SystemRoot%\System32\wiaaut.dll HKEY_CLASSES_ROOT\CLSID\{850D1D11-70F3-4BE5-9A11-77AA6B2BB201}\InprocServer32 Link to comment Share on other sites More sharing options...

toe_head2001 Posted February 20, 2019 Share Posted February 20, 2019 If you're missing wiaaut.dll , you need to run the SFC command. https://support.microsoft.com/en-us/help/4026529/windows-10-using-system-file-checker My Gallery | My Plugin Pack Layman's Guide to CodeLab Link to comment Share on other sites More sharing options...

hooddy Posted February 20, 2019 Share Posted February 20, 2019 Ok i got it. WIA service was disabled. Its really strange that for printing used scanner service. Even strange coz it runs system image viewer for printing which works well with no WIA service enabled. Link to comment Share on other sites More sharing options...
