bmrstadm appcrash and Netbackup stopped working during SRT creation for windows server

Hi All,

We are performing restore of BIS server. As part of SRT creation, after installing netbackup client and patch, we were trying to add WinPE drivers to the SRT. After copying the nic folder, on clicking the Explore SRT button, it is showing the error message of bmrstadm appcrash and "NetBackup has stopped working". This issue is not reproducing. Can anyone of you please let me know what mighte be the reason for this?

Thanks in advance
