UsingEnterprise workspace 1.1 in SAP Portal 7.4

Hi Experts,

Need you help.We want to use Enterprise Workspace in SAP Portal 7.4 and we have deployed below SCA's for Enterprise Workspace 1.1-

EPEXT01_0.SCA

SPACES01_0.SCA

SPACESAPI01_0.SCA

SPACESAPPS01_0.SCA

SPACESKM01_0.SCA

Workspace Administration is available in Portal after assigning "Workspace System Administration" role , but while trying to Activate People explorer in Workspace Adminstration->Configuration->tools --I am not able to find any People Explorer Tool here

Also, if I try creating any new workspace I am getting below error-

Error: Application error occurred during the request processing.

Do we have to deploy any other SCA apart from these??

Please reply if anyone is aware of this issue.
