I desperately need your Help!!I have Mozilla Firefox and I want to install Internet Explorer 7 but when it starts extracting the files a window pops up saying it could "not verify the integrity of the files necessary. Please check if the cryptographic service is running on this computer"

I have found a site of microsoft about the problem where it says I should go in cmd and give these commands

net stop cryptsvc
ren %systemroot%\System32\Catroot2
oldcatroot2
net start cryptsvc
exit

and then retry installing it. But as I write the second line - after the first command is succesful - it says the syntax is not correct. How could I solve this problem?Are the % and \ to blame???

What Micro$oft site did you get this info?

You must make sure these Win XP services are enabled and running:

Cryptographic Services
Remote Procedure Call (RPC)
System Restore Service

Go to Start menu >Run > MSCONFIG <enter>

Click on the "Services" Tab & review these services. They should have a green "tick/check" mark on left; and status "Running" on the far right.

I just checked the three services and I found out that there were 2 RPCs in my computer, the first running and the second stopped, but both of them ticked. Why are there 2 RPCs??

The site is in the Hellas Microsoft and it' s written in Greek, but I' ve also found the following:

As I already said I tried to do what it says in the cmd but the syntax is incorrect

I tried the 4th helping point and it did help!Thanks! But a new problem occured:

I have Windows Home Edition SP1 and it says that my operating system does not support IE7.


But when I tried to install IE6 it said there is a newer version already installed in my computer. Which version could that be between IE6 and IE7????I will go mad soon!

Then, I searched in Add/Remove programmes but there existed no IE!

I don' t know where it is located. Then I went to Search and I found 14 files of IE, none of which function properly and furthermore I can't delete them!
