New installation of vSphere 5.5a on a Windows 2008 x64 VM with all componenets (SSO, Web Client, Inventory and vCenter)

Cannot get Web Client to work, unless I install it to a path with no spaces, ie E:\vmware\

I get the error: The requested resource is not available with a 404 webpage when trying to access https://serverFQDN:9443

I have seen article http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2044953

but it makes me no wiser as it states C:\Program Files\VMware\Infrastructure\

If I stick with E:\subfolder\ it works fine

Anyone found a way to install the Web Client to path contining spaces?

Thanks for any input,

M
