How can I install the windows installer 5.0?

I have been trying to solve this for quite a few days now. Everything that is Posted out there does not work. I have Windows 7 and I tried to install Service Pack 1... it failed. Ever since then, Windows Installer cannot be accessed error 106 keeps coming up when I try to install anything. Also, windows Media Player does not work either. I have tried everything that is posted out there for a fix. I tried the whol msiexec/unreg and msiexec/regserver I have tried the hot fix patch that is supposed to work, still doesn't. There is no distributive pack out there for Windows Installer 5.0 so I can't download a new one.  I have tried the sfc/scannow and that cannot run, it says my PC needs to restart and I have restarted again and again and still the same thing, it will not run. I can't tell you how many other things I have tired. When I run msiexec.exe I get no errors and this screen comes up:

So I can't get anything to install and I can't get this issue resolved. Does anybody have an actual answer to this problem?

Did you get any answers? I have a similar problem.

I'm having problems with my widows installer 5.0 also.

Have windows 7 home premium, 64 bit.

I have been trying to solve it for 2 days now. I get the folowing message everytime I try to install the program.

"This installation package could not be opened.Verify that the package exists and that you can access it. Or contact the application vendor toverify that this is a valid windows installation package.

I've contacted the vendor, but have not recieved an answer.

Everything I've done or checked claims my computer does not have a problem.

Would appreciate a reply if anyone has run into this also.

Thanks, Ray

Hi mrclean85,

1. What is the issue with Windows Installer?
2. Do you have any issues installing any program?
3. Do you get any error message related to Windows Installer?

We cannot install Windows Installer 5.0 as it is the default version in Windows 7. If you can provide us more details about the issue, then we can assist you better.

If Windows Installer is malfunctioning, then try to Unregister Windows Installer, and then reregister Windows Installer. To do this, follow these steps:

a. Click Start, type cmd, right click cmd and click run as administrator.

b. On the command prompt, type "msiexec /unreg" and then press ENTER.

c. On the command prompt, type "msiexec /regserver" and then press ENTER.

d. Check the difference.

I think you are dropping the ball.  Release a damn patch and save us all some valuable time.  I've spent far too much on this stupid problem YOU should be able to fix easily.
