We are getting below error while installing content porter from CME- using IE

  • application validation did not succeed. unable to continue

  • File, Tridion.ContentManager.ImportExport.CommonFacade.dll, has a different computed hash than specified in manifest.

This happened after we tried installing a patch for CP(hotfix

Can some one suggest a solution.

--- We are in the process of Upgrading to Sp2 Content Porter and the issue is resolved.

Could you please let us know, what was actual issue & how did you resolve it? – Raj Kumar Feb 20 '14 at 3:48
We have opted to upgrade CP to SP2 to avoid further issues with patching. – Ajo Mathew Feb 20 '14 at 13:24

It seems conflict issue of older and new dlls. Restart your Tridion services and reset the IIS pool of SDL Tridion website.

I have updated my answer, please check if it helps also Google about "ClickOnce Deployment Issue" if above links do not help – Raj Kumar Feb 18 '14 at 11:49
We first checked on One Click Deployment. As part of applying patches(ID mentioned in question) we have replaced few dll files later we reverted with backup dll files. Upon restarting COM+ we faced this issue. – Ajo Mathew Feb 18 '14 at 12:07
MSDN link above talks about different set of problems and their solutions related to click once deployment, i think you should give it a try(if not already tried) after patching Content porter again.. – Raj Kumar Feb 18 '14 at 12:38

We are in the process of upgrading the CP to 2009 SP2 to avoid these issues with Patches/reverting as final solution.

For SDL Tridion SP1 HR1 try to install Content Porter 2009 SP1 just with Hotfix 75326. It has been working on my previous installations without any related issues.
