Q: windows error 193

Hello there! I am still having this problem, and I have read all of your advice. I know how to fix my iTunes, but my computer seems like it is refusing to fix it. What should I do with this, when my computer is already set as an administrator?

For general advice see Troubleshooting issues with iTunes for Windows updates.

The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach.

The further information area has direct links to the current and recent builds in case you have problems downloading, need to revert to an older version or want to try the iTunes for Windows (64-bit - for older video cards) release as a workaround for installation or performance issues, or compatibility with QuickTime or third party software.

Review the other boxes and the list of support documents further down the page in case one of them applies.

Your library should be unaffected by these steps but there are also links to backup and recovery advice should it be needed.

The for older video cards version may well prove a viable workaround in this instance.

ADDITIONAL FIX - IF ALL ELSE FAILS

(For Windows computers - not sure if it's the same for Mac but worth a try)

If all the above still doesn't work (and everything else you try that you have read on the internet like me) I have just spent an hour on the phone with a senior support tech from iTunes and finally found the problem.

1) Firstly I uninstalled everything 'Apple', see here - Remove and reinstall iTunes and related software components for Windows Vista, Windows 7, or Windows 8 - Apple Support

2) Then go to 'C:\Program Files\Common Files\'  and delete the 'Apple' folder if there is one. Do this also for 'C:\Program Files (86)\Common Files\'

3) OK now here is what I did differently. Open your file search 'C:\' (click the Start Menu --> Computer --> OS (C:). In here search in the top right for the following file 'msvcr100'. It is a .dll file.

4) Click the one titled exactly 'msvcr100' (there might be another one with a longer name ignore that one). Drag the 'msvcr100' file to the desktop, DO NOT delete or copy it (yet).

5) Now go to iTunes.com and download the latest iTunes (probably save it to your 'Downloads' folder). Once downloaded RIGHT CLICK on the newly downloaded setup file and click 'Run as Administrator' (this is important).

6) Follow the usual iTunes installation guide and it SHOULD install OK. If it does then you can now delete the 'msvcr100' file from your Desktop.

If it doesn't work then I would get iTunes Support to ring you. Here's the link to the support - https://getsupport.apple.com/

Hope this helps people! Good luck

THANK YOU SO MUCH!! This was the only suggestion that helped me. I, like everyone else, tried all the other suggestions found in the community and yours finally worked! Thanks!!

OH MY GOSH!!! THANK YOU SO MUCH! I'VE HAD THIS PROBLEM FOR ALMOST 5 MONTHS NOW, and now I fixed it!

Hello. I just recently started having issues with this, 'iTunes was not installed correctly. Please reinstall iTunes. Error 7 (Windows error 193)' window pop up and I've have tried everything I can to try to make iTunes work. I just upgraded to Windows 10 so if anyone and help me out with some instructions on how to get this fix, that would be awesome. It's been a month since I havent listen to my music on my PC.

Try http://go.microsoft.com/?linkid=9779673, a Windows 10 compatible version of the Microsoft Program Installer & Uninstaller Fix-It tool. This may be able to push through the uninstallation or installation of the various iTunes components.

I tried it and it did not work at all. I even tried to delete all the Apple stuff and I re-installed it but it still does not work. It has to be the Mobile Support Device thing that's causing this issue. Can you give me another way to get this fix.

See the method in Install missing components. What component fails to install, and what error message does it give? See this post for steps to produce detailed logs of the installation which may reveal why iTunes won't install. Look for keywords such as failed or error.
