Error: 'Unable to initialize the host process' while connecting Recovery Manager for Exchange to (4256018)

During the connection to Tivoli Storage Manager (TSM) from Recovery Manager for Exchange the following error occurs:

Cannot continue because this host process is unavailable: QuestSoftware.RecoveryManager.Host64.exe

Details: Unable to initialize the host process.

Recovery Manager binaries are signed using a digital signature (provider: verisign.com). During the start of RMEX the OS tries to verify signature by accessing clr.thawte.com or clr.verisign.com. These sites are not accessible and this verification process takes more than the default startup timeout (30seconds).

* Allow access to *.thawte.com:80 and *.verisign.com:80

OR

Disable signature check.
To implement this create a file named QuestSoftware.RecoveryManager.Host64.exe.config and copy/paste the following information to this file:

<?xml version=1.0 encoding=utf-8?>
<configuration>
<runtime>
<generatePublisherEvidence enabled=false/> </runtime> </configuration>

* Copy created file to folder D:\Program Files (x86)\Quest Software\Recovery Manager for Exchange.
