Error 1723 - Unable to install anything with a .msi installer

Robwan said:

No I just used ccleaner.

After I did the repair install yesterday, I did all the windows updates then checked to see if a .msi file worked and it did no problem. Only today i went to do a cclean and then tried to install a .msi afterwards...which was reallllly stupid, I should have tested a .msi right before and after cclean to pinpoint it.

The second repair install has just finished now, and .msi files once again work, hooray. However I don't know whether its worth trying a cclean, if it does screw it up then its good and bad as we have pinpointed the problem, but it means I'll have to do a third repair install; I am curious though. To test it i might make a backup image with macrium before hand, as I've always wanted to restore an image just for the experience of doing so.

Any ideas on what you think it could be? I checked my ccleaner settings on my pc and they seem to be the same as on laptop. I'm kind of expecting the problem to come back.

One thing that might be a clue maybe.

After the upgrade finished and my desktop loaded, I was greeted with the notification
"Setup has detected that .NET Framework 4 needs to be repaired. Do not restart your computer until the repair is complete."
Maybe this is was needed repairing? I don't know, but it took about 10-15mins to repair for me. (this happened on both repair installs i did)

Thanks again

Test whatever you want. You learn a lot of it. What I would do:

• Test if everything is working fine now. Especially MSI problems
• Make a backup
• run ccleaner
• Check msi problems again

If msi problems again:

• uninstall dot net 4
• reboot
• try to install msi again

permissions on %temp% can be the problem. Check the permissions now please. System, Administrators and YOURSELF have full access? Press "advanced" ... all permissions are inherited from C:\users\yourself ?

Ok so i checked the permissions and looks like I have full control (image), however, I'm currently not getting the 1723 error anymore since i did the repair install a second time.

I think i better get to bed now anyhow as its late here in uk, but Ill keep and eye on things and be sure to report back if the problem reappears, as I imagine it will do, then I will check the permissions again. Thanks for all your help though :)

Please post same screen again if error 1723 comes back

Ok bingo, I've managed to recreate the problem and then fix it by changing the temp folder permissions (I attached an image showing how my permissions look when the problem is present, when my permissions are like this I will not be able to install msi's and will get 1723 error. Upon changing them back to full control everything works fine and msi's work.

Ok I am pretty sure the cause is adobe acrobat pro, which is slightly odd, I don't think its a coincidence because I tested my theory about 4 times to recreate the problem. To test it I did the following:

• 
  
• Open a file using acrobat pro
  
• Then try to run any msi file, the msi would actually work maybe the first time with no error, then i canceled the instillation and try again and I will get error 1723 or any of the other similar errors pictured in my first post.
  
• At this point I checked my temp folder permissions and they are all changed (like in the picture attached here)
  
• After changing them back, all msi's work again, then I can recreate the problem again and fix by going through the same process.

If I'm correct, I am clueless as to why acrobat is causing the folder permissions to change? is this something to worry about?

Thanks

Delete all permissions on temp folder. Place check mark at "include inheritable permissions from this object's parent". Did you do that?

check the permissions on temp folder just before and just after using acrobat pro. That proves acrobat pro does create the problem. Please test it

All other files are still in TEMP?
