Just a heads up for anyone who may install the IPM module of CW in the near future. When selecting a custom installation directory, do not use spaces within the folder name.
I recently had issues with my installation where i chose to install into "D:\Internetwork Performance Manager". This lead to installation hangs and the service not starting corretly. After opening up a TAC case, the solution was to attempt an IPM re-install using a directory structure without spaces. Installing to "D:\IPM" resolved the issue :)
Apparently there is one or more xml files that dont like the spaces. Cisco hasnt been able to consistently replicate this issue, but some other customers have had the same thing happen.
