Problem with CS5 / Flex 4.5 : Installer has detected that a machine restart is pending (solved!)

October 26th, 2010 by Slav

Few days ago , Flex 4.5 Burrito and SDK Hero was again  available for download so I went and downloaded the whole half a gig enchilada.  After running the installer there was a warning : installer has detected that system restart was pending but that could be ingnored so I went on fit the install.

Install failed miserably about the time it tried to install some microsoft libraries. Oh joy. Well , at least ALL it’s needed was a machine restart, and all would be jolly good right ?. Or so I naively thought. I couldn’t be more wrong.

No joy. The same error message. The same install fail :(

After unsucesfull googling and restarting couple of times I gave up and went to bed as it was well after my usual bedtime (1 am)..

Evening of day two…

More googling. Finding out many more people have the exactly the sameproblem with other CS5 installers , but none of them had actually any luck in resolving the issue (or bothered to write about it).

Official Adobe solution to this problem is :

a. Choose Start, type regedit in the Search box, and press Enter.

b. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager.

c. Delete the InProgress key

as stated at :

Now that would be awesome, if there was actually any “InProgress” key in my registry. If you read comments, that was mostly the case with most users so this advice was pretty useless.

OK. to make a long story short, I did find somebody suggesting to erase : “PendingFileRenameOperations” from registry from a certain location.

I did not find any keys in that particular location, but searching troughout the entire  registry for “PendingFileRenameOperations” revealed couple of instances.

I deleted them all and voilà ! the installer ran like a charm!

So if you have the same problem with the CS5 installer, try it, might help you as well.

Word of caution . Make sure your registry key has a NAME that matches “PendingFileRenameOperations” as there might be some keys that have this string as a data/value.

in my case it was :  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\BackupRestore\KeysNotToRestore” key which value/data contained string “PendingFileRenameOperations” .

Do not delete those :)

    Thanks a lot Slay. My ***?#%! CS5 product has the same problem! You save me many more hours of my time!

    Thanks again!

    Thanks Slav. That worked. I found two instance of PendingFileRenameOperations and rather than delete I renamed them both PendingFileRenameOperations2.

    Interestingly, the data linked to this key points to two logitech cam dlls – LVPrcInj01 & 02 which are located in WINDOWS\TEMP\logishrd. Not sure what to make of these files and will look into getting rid of them.

    Thanks again.

    Man you are a lifesaver. I went through precisely the same thing that you did, tried restarting a few times, no luck. Checked adobe online support, couldn’t fine the InProgress key either. Called Adobe support and landed this complete idiot who didn’t know a thumb drive from a floppy disk and just about went insane. I tell him the problem and he asks if it happens when I am extracting the files. I say no it happens when I’m installing … three minutes later he says “just to confirm this happens when you try to extract the file right?” …wow. Then said “so you are experiencing trouble extracting the file?” DOUBLE WOW. Then he says “please hold a moment while I research the problem” and comes back with “delete the InProgress key” … research my butt I can use Google too moron I need someone who actually knows how to really fix it not regurgitate recycled broken fixed from’s website LOL.

    He wanted me to go out and buy a 7 GB thumb drive so that I could copy the entire Photoshop CS5 download over to it, then create a new user profile on my computer then copy the adobe folder from the thumb drive back onto my hard drive and try installing it from the new user profile. Really?! That’s the best that big bad Adobe can officially do after I spend $200 on their software? Are you kidding me?

    He put me on hold again when I asked to speak to level two tech support and, while I was listening to elevator music I found your website, tried it and was installing before the idiot even came back on the line. When he did come back it was to tell me that level two support was not available and my response was “I googled it, I solved it, I don’t need you. Your tech support sucks!” lol!

    Thanks for the article!

    Lynsee: that seems like a very poor level of customer service from Adobe. Something like this happens to me when I try to reach customer support of a major telecom corporations here in the UK and I get a guy in India that can barely speak English and has a couple of scripts that he follows.. Wouldn’t expect this from Adobe though. 200$ ? Try 1000+ ! Here in the UK they have a different pricing policy :(

    I’m a bit illiterate when it comes to “registries” and “keys” and whatnot… I’m a bit confused. I found two files that match the “PendingFileRenameOperations” name – but they are in the “KeysNotToRestore” thing that I think you referred to… I did a search for it, but nothing came up as far as “keys” go…

    Absolutely fantastic, thanks for making the article, such a saint!!!

  13. Chad

    Thanks. In our case it was an instance of the “ask toolbar” (borderline malware…) that was holding that keyword. Deleted it and all is well.

  14. Curgan

    Thanks for the post. However, I’ve followed the steps completely but i’m still getting the same annoying message “installer has detected that a machine restart may be pending…”

    In my registry, I found “PendingFileRenameOperations” and “PendingFileRenameOperations2” I deleted the first one(without 2) yet its still not working. Do I need to delete the two of them? Please I need your help. Thanks in advance.

    I tried all of the above and still cannot get rid of the “restart pending2 bootstrapper error has occurred, issue. I have no InProgress key nor any PendingFileRenameOperations keys.
    Anyone anymore ideas pls?

    Also is the an Adobe issue or a windows issue pls?


  26. LitSpirit

    When all else fails try this… Start > Computer > C Drive > Program Files > Common FIles > Adobe …look for the file named OOBE and rename it adding the word old ‘OOBEold’

    Then go to install and ignore if it says restart pending, it may take a while but it pushes through to the install!!!

    I trust that works for you
