Little surprise today when I tried to install this Management Pack directly from my RMS which is hosted on Windows 2008 x64:

First I thought it was just a file corruption so I downloaded it again and same result.
Then I discovered here that this problem was introduced in the 1.5.2 version. No comment.
My workaround was to install it on a x86 machine, then copy the C:\Program Files\HP\HP Enterprise Storage folder to the RMS (same path) and finally import the management pack stored in the folder. I don’t mention here the WEBES and Webes listener installations.
I don’t have any issue atm but I’ll let you know if any problem appears. Alerts (test one) are correctly forwarded:
