Thanks,
Yes I,m installing to domain controller server.
I installed according to Implementation Quide --- not according to readme file. So I didn't uninstall AUTODESKVAULT and Vault databases.
Same error appears with username "our_domain_name\AutodeskVault" with default password. Response is "Value cannot be null. Parameter name: path"
Please see attachment EDMLog.
Please give me quick response,
Jude
