Cannot Install apps in windows 7

[Sl@pSh0ck™]

Okay, I uninstalled an app through revo uninstaller and then run ccleaner afterwards ... now when I am trying to install app it would give me error saying the "windows installer service could not be accessed" ... I have set windows installer and trusted installer services to automatic to no avail. I have unregistered and then re-register these services but still no go. I tried to do sfc /scannow but it says "windows resource protection could not start the repair service". I am not at home right now so I don't have access to my install cd to do an offline sfc /scannow. I am sure revo/ccleaner mmight have removed some registry keys associated with these services.

Any ideas what I can do without resorting to sfc /scannow coz I don't want to lose any customization settings I have ATM. Any help would be appreciated. Thanks.

My link

Thanks for the reply bro ... but after following the instructions from that link I am still getting the same error message when trying to install anything.

... and same error message when trying to run sfc /scannow

Try Start>Run and type in "net start MSIServer" without the quote.

Oh...and Windows Module Installer should be in "Manual" in Services.msc

Windows Installer should be in "Manual" too.

[Sl@pSh0ck™]

Try Start>Run and type in "net start MSIServer" without the quote.

yeah have done that as well .... I have even set those 2 services to start automatic - restart, but then same error message.

[OhMyGod]

On Revo Uninstaller's settings do you have it set to "make a System Restore Point before uninstalling"?

If so then simply do a System Restore to the point before you uninstalled that application.

I believe when you deleted the registry keys for that application you didn't select the end keys, you might have deleted the root key for Windows Installer.

If you didn't make a System Restore Point, then you might have to do a repair with your Windows disc.

Thanks.:)

Look like you have to repair by pressing F8 on reboot.

Or try this first, in services.msc>Remote Procedure Call (RPC)

Select Log On In Tab

Select Log As "Local System account" and tick "Allow service to interact with desktop"

You'll get a message that settings wont take effect until you restart the service. To do this you'll need to reboot your PC.

Hope this work.

[Sl@pSh0ck™]

Yeah, I think I will need my installer disc to repair this .... sfc /scannow on safe mode gives me the same error message.

I don't have any restore point setup in this laptop so restoring is not an option for me :lol:

Will deal with this tomorrow @ home... time to go to work ... thanks guys will keep you posted how it goes.

[KotaXor]

Did you try this in cmd prompt:

regsvr32 c:\windows\system32\msi

Hope this work.

I think this service has the problem .... On log on tab ... all options are grayed out for me .

if all else fails put in your installation cd whatever your o/s boot to disc and choose repair and this should renew all your files. . you may have to go into updates to restore windows installer good luck

[HX1]

After you uninstalled the app, did you reboot? Thinking that it could be locked for finishing the operation after restart..

[Win7nerd]

Use tuneup utilities then find "fix common errors" find fix windows installer restart see if that helps

[Sl@pSh0ck™]

@heath

yeah i did reboot several times already to no avail.

@win7nerd

I used windows 7 manager to try fixing this issue but it is still dependent on the services affected so no go as well.

Will try offline sfc /scannow and see if it would work.

[HX1]

Read where a PC Tools Firewall Plus blocked the Windows Installer...by default.. and your services should be set to Manual... Not Automatic from what I am reading.. Is there a msiexec running in Task Manager? and take a look at this.. http://www.winhelponline.com/blog/fix-for-error-windows-resource-protection-could-not-start-the-repair-service-when-running-sfc-in-vista/ I know its about Vista but these areas may be similar and worth checking.. I think after that you may then try this which I think you have done once already.. http://www.winhelponline.com/blog/vista-the-windows-installer-service-could-not-be-accessed/

EDIT: Link disappeared or I forgot or something.. Sorry..

[KotaXor]

running out of idea other than sfc /scannow.

How about trying this registry tweak:

Losing hope now .... was able to run offline sfc /scannow but still the issue persists. Even worse after sfc /scannow some of my apps are not running anymore eg. office 2010 ... cannot install windows update as well.

Will try this reg fix ... thanks kotaxor

[Sl@pSh0ck™]

I have merged the reg fix ... restarted but no luck :s ... will try another offline sfc /scannow and if this issue persist ... will reinstall win 7 :fear:

[HX1]

One more link with quite a few of fixes listed for similar.. Your other apps probably just need to be 'fixed' again.. Your issue is relative to some of the other problems I have been reading about.. in researching it..

http://en.kioskea.net/forum/affich-390-windows-installer-service-could-not-be-access

Don't forget to run CMD as Admin...

[KotaXor]

This is bad...even sfc /scannow does not work....running out of idea.

Re-format? Last resort?

[HX1]

Thats what I posted about post before last... There is a service relative to Trusted Installer.. and a process to address it.. but thats if you also have a problem with sfc.. but still could be something..( one of the reason I hate uninstallers .. ) I can do most of that stuff myself.. without it.. but this should be fixable.. easy way.. would be to do a fresh install IF.. the damage has been done.. but always as last resort... there has to be a reason that none of this is making any difference.. I would scan the registry for anything out of the ordinary.. or do a backup from last registry clean if possible.. then clean it again.. to remove the recent invalids.. but all of this is feeling around in the dark...

[Win7nerd]

Try the windows repair option maybe?

[Sl@pSh0ck™]

I gave up :blink: .... reformat and fresh install of windows 7 ... issue fixed :lol:

Thanks a bunch to you guys for the help :wub:

[avmad]

I had the same problem many times with vista, scoured the web for fixes, and tried allsorts. In the end I kept making things worse and had to do a fresh install. Then when it happened again I installed windows 7. Im sure I managed to fix it a couple of times (cant remember how though :angry: )

Now I seem to be able to install programs, but they wont all run :angry: Simple Port forwarding always says its stopped working as soon as I click on it. And also TUT, run it and nothing happens. I wonder if I've been banned or something from using moody copies in the past. Drives you crazy.
