TRying to solve Windows Installer problem

[tetsuo]

I am trying to use a programm (which is a msi-file) and want to install it. I could do that after running the All-in-One package and restart my computer (with Win7). Once restarted I need to double-click the msi-file ASAP. If I am too slow, and yes that happened three times before I found out, it seems that all of the repairs have been unfixed and now have the same state again. But I got the chance to install it, and run the prog once. After I exit it and want to start again, it was all the same. Every time I want to start it, I need to run the Windows Repair tool.

I am using Panda Cloud and Spybot plus installed SuperAntiSpyware and MalwareBytes after having troubling and I want to check for possible infections. Nothing has been found.

Anything someone can tell why something is going to be unfixed again after repaired with Windows Repair?

What is the error you get with MSI when you try?

Can you post a screen shot?

Unfortunately I can only provide you with an error message, it was like: "Windows Installer service could not be accessed" plus some other words I forgot.

Since the last fresh start of my computer after I uninstalled Windows Repair All-in-one, SuperAntiSpyware and Malware Bytes. All's working fine. Also neither AntiSpyWare nor Malware Bytes found anything unusual. I even could install another programm via MSI file. Absolutely don't know what has changed since last night. I couldn't even start a MSI file now I have two programms installed via MSI files And both work fine.

It sounds like the permissions keep getting changed, was it just the one program or is it any MSI program?

Few days before I tried to install said programm I have installed a MSI-based programm. That worked fine.
It never happened before.

You mean the permission when I right-click a file, right? How could they change automatically?
Or do you mean "Services" -> Windows installer and these permission for that Service?

I mean you could have something messing with the permissions of MSI, some viruses and rootkits do that so you cant install a scanner.

I am using a cloud anti-virus tool, but will scan tonight with an online scanner. Just to make sure. Any recommendations?

Combofix.exe and malwarebytes anti rootkit tool.

I would also suggest sfc /scannow. It will fix most programs, if it is run to 100% without problem.
                    There is no fix for windows installer other than trying to create a new ac having administrator power and then copying user account files as per microsoft instructions. You can copy all the folders after creating the account and  with out Ntuser.log, and other logs as per microsoft instructions.
