high quality heart – “Unable to open the [test name] take a look at.” message when beginning QTP autotest from QC

I’m integrating QTP 11.0 autotests with HP ALM 12.20 so I may run them instantly from ALM. So I’ve carried out all the pieces in accordance with High quality Heart – QC-QTP Integration:

• put in QuickTest_Add-in_for_ALM-QC
• arrange HP ALM connection to QC
• saved the take a look at in High quality Heart Check Plan
• added Check Assets (Shared Object Repositories, libraries)
• added Check to the Check Lab and executed take a look at

However the issue I’ve received when beginning take a look at from HP ALM’s take a look at lab is:

BTW: there was a time when the take a look at executed as soon as, however then the issue got here again once more.

Additionally tried:

• grant entry to everybody to the person temp space (%USERPROFILEpercentAppDataLocalTemp)

Does anybody know what to do?

Additional questions / information to clear up issues:

1. Are you able to open take a look at information utilizing QTP from ALM/QC Check Plan (as for me, after ‘Save as’ operation, I’m attempting to open the file and I’ve received the message "Check [test name] doesn't exist")
2. In Check Plan on the tab Check Script of the autotest the message is proven "Cannot load take a look at from C:Customers[user]AppDataLocalTempTD_80876732cc74Test110711071107", however nonetheless once I shut it there’s a form of take a look at construction displayed in Key phrase View. However once I open this path from QTP all the pieces is ok!
