hi,

for last Deski report  we want use DCP... BOXI31sp7 have been installed on clean windows 7 client machine after this we have  installed BI41sp5 client tools.

We can login  (administrator account...) with deski on BI4, but can't import or export Deski document...

import error = 'repo_proxy 28...document facade...local file copy has failed. File repository Server error'

export error = 'repo_proxy 30...objectexport...commit. File repository Server error'
