Dell / INSPIRON 1500
August 18, 2009 at 08:37:03
Specs: Windows Vista , 3.G
I recently purchased a Dell Inspiron Laptop with Vista Home Premium. When i attempt to install a VPN client i get the following message;

Error 1721: There is a problem with this Windows Installer Package. A program required for this install to complete could not be run.

Has anyone encountered this? How can i fix it?

btw, i did a search on this site but it wasnt yielding any positive results. The search field was too general.

Thanks

I believe thats relative to the Exchange Best Practices Analyzer 2.8, that isnt what im trying to install. Although i understand that its the same error message, the resolution ask's me to install the Exchange Best Practices Analyzer 2.8 which i believe I have no need to install this.

Suatnici,

I think we use the same searches. I did each of those steps yesterday but am still having the same problem.

I did notice upon doing the Windows Clean Up utility listed in your second option, the results received were that windows had some corrupt files that could not be fixed. It still allowed me to reinstall the Windonws Installer 4.5 but did not fix the problem.

Do a CHKDSK /R /F at a command prompt with Admin Privileges and see if it corrects corrupted file system/hdd sectors.

Dear toicy4ya,

You have done what others did to eliminate their problem, but your PC seemed to be stubborn and you are unsuccessful.

I suggest you follow again every step given to you above and retry. If not successful, you may try restoring your PC to a time before the problem appeared. If still not successful, you may attempt to re-install Windows and all your programs from scratch.

Hope the above helps.

Regads

I suggest you should install Vista service packs, SP1 first and SP2 last if you do not have them already installed. This may resolve the issue.

Short story: Are you sure that the VPN client you are using supports Vista x64?

Longer Story:

You didn't say, or I skimmed to fast to be sure, but I know some the the users I support encounter this error when they attempt to install the Cisco IPSEC VPN client.

This is because the last time I checked, the Cisco IPSEC VPN client did not, nor did they have plans to provide, support for Vista x64.

Cisco has told us to use an alternative client which required that we upgrade our concentrator. that was an SSL VPN client that was installed through a website.

Yes - I'm using Vista 64 bit. Just read that Cisco doesn't support it. I'm downloading this: http://www.ncp-e.com/index.php?id=9...

The NCP Client I mentioned above did the trick. It's a 30 day free trial.

Now after spending all day at work, I can once again resume working in the evenings, weekends and occasional holidays.
Yipee! ;)

Bob,

what did you have to do to get it working? Is the ncp client
like a patch? Does it work with cisco?

I appreciate any help you could offer.

Thanks

It's not a patch. It's a third party product. It worked.
