I am using windows 7, 64 bit, CCleaner freeware.
Before I make a donation, I ran Cleaner & everything worked fine.
I then ran CCleaner "registry" (included Registry backup before fix) & ended up getting an TrayApp.msi error everytime I log onto my computer.
After review of the problem, it appears that the best (& probably only) cure is to restore the registry from the backup.
I am unable to access a method of accessing the registry backup from within CCleaner.
According to the CCleaner WEB site, "Using Windows Explorer, navigate to the folder with the Registry backup (a file with the extension .REG). By default, CCleaner stores these backups in your My Documents folder."
The registry backup file in was not in "My Documents" folder. Also, the backup file name extension is not "reg" it is; ".regtrans-ms".
When I run Regedit, I cannot import files without an File name extension of .reg. It will allow me to import a backup file named ".regtrans-ms" as a "Registry Hive File"
By one CCleaner instruction I am to right click the respective back up and click merge.
When I right click .regtrans-ms, there is no "MERGE" selection. The only reasonable selection is "RESTORE PREVIOUS VERSION".
By another CCleaner instruction, I am to; "Double-click the Registry file". You are prompted to confirm the action: Click Yes to restore the Registry." When I "Double-click the Registry file" a window pops up that says "Windows can't open this file".
Bottom line is that I am I am afraid to use any of these procedures!
How do I safely restore my register?
This info is provided to clarify what happened.
The first time I got a “TrayApp.msi error” when I log onto my computer was just after running “Ccleaner”, "Registry".
I researched of the “TrayApp.msi error” on the WEB.
One source indicated that noted the problem occurred right after running a “registry repair program” and was able to repair the problem by inserting his “HP Printer Installation disc”, locating a file named “TrayApp.msi” and installing it.
I have a HP Photosmart C5180 All-In-One Printer-Scanner-Copier that didn’t have an installation disc. It is “Plug & Play” and as such installed when it was plugged in. In the interest of correcting the problem, I disconnected the printer, uninstalled it and all its associated programs. I then reinstalled it by reattaching it to my computer system. The “TrayApp.msi error” problem persisted.
I searched HP & Microsoft for a “TrayApp.msi” file to install or an alternate fix. None were in evidence.
Another source that offered a fix noted that the problem occurred right after running a “registry repair program” and was able to repair the problem by restoring the “registry”.
Since I couldn’t remember where the .reg file was saved or what the file name was, I ran a search for .reg on Drive C (search-ms:displayname=Search%20Results%20in%20HP%20(C%3A)&crumb=fileextension%3A~
<.reg%20OR%20System.Generic.String%3A.reg&crumb=location:C%3A%5C).
I also ran a search for *.*reg* on Drive C (search-ms:displayname=Search%20Results%20in%20HP%20
(C%3A)&crumb=fileextension%3A~*.*reg**&crumb=location:C%3A%5C) which resulted in the same results.
The location & file name was;
C:\Users\Chuck\NTUSER.DAT{016888bd-6c6f-11de-8d1d-001e0bcde3ec}.TMContainer00000000000000000001.regtrans-ms
