Just after I tried to install the addons the following error was displayed after a reset as the machine was quite slow, perhaps it was taking too much memory.
Result Code:
E_FAIL (0x80004005)
Component:
SessionMachine
Interface:
ISession {12f4dcdb-12b2-4ec1-b7cd-ddd9f6c5bf4d}
Is there something I can do about this?
