Hi Paranormastic,<br />
<br />
Sorry for the late response. I was out of action there for a while. I had a look at your solution this week and it worked a treat. <br />

Many thanks,<br />

Hi there,<br />
<br />
I renewed my Comodo code signing certificate and generated my pfx file from the pvk by using:<br />
<br />
Pvk2Pfx –pvk mypvkfile.pvk –pi mypvkpassword –spc myspcfile.spc –pfx mypfxfile.pfx –po pfxpassword –f<br />
<br />
When I used this pfx file to sign the assembly in Visual Studio I got &quot;Error Importing Key, Cannot find the certificate and private key for decryption&quot;. <br />
<br />
So, I followed this link <br />
<br />
<a href="https://support.comodo.com/index.php_m=knowledgebase&_a=viewarticle&kbarticleid=1078" rel="ugc">https://support.comodo.com/index.php_m=knowledgebase&_a=viewarticle&kbarticleid=1078</a><br />
<br />
which created another pfx file for me which has a different name to the first pfx file in this scenario.<br />
<br />
Now when I use this pfx file to sign the assembly I get: &quot;Error Importing Key, Object already exists.&quot;<br />
<br />
Any assistance with this is greatly appreciated. I had no problems using the Comodo cert last year just with this new one.<br />
<br />
Regards,<br />
Nicola.
