Q. I get an error from the IIS when I try to open the Daminion web access page. The error is the following:

CS0016: Cannot write the following: “c:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files\daminion\c1e4c4c2\9dd32e5c\App_global.asax.pum7vdiu.dll” output file – „Access denied”.

A. Can you please go to this folder:
c:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files

Right-click, go to the Security tab and read/write permissions to IIS_WPG and NETWORK SERVICE users.

Please also grant permissions to C:\Windows\temp for these users
After that please restart Daminion Server.

You can also click on the Reinstall button in the Administration > Web-Access window
This is the ASP.NET access rights issue. More info about this issue:–could-not-write-to-output-file-microsoft-net-framework-v4-0-30319-temporary-asp-net-files

Q. I get an error:

Service cannot be started. System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. —> System.ArgumentException: The certificate ‘CN=localhost, OU=Debug,, S=Russia, C=RU’ must have a private key that is capable of key exchange. The process must have access rights for the private key. —> System.Security.Cryptography.CryptographicException: Keyset does not exist

A. If Daminion Server wasn’t launched in normal mode, and you see the info about the certificate access issue please do the following steps:

– grant access rights for Daminion Server user to this folder:

– launch this command line for the Server version:
c:\Program Files (x86)\Daminion Software\Daminion Server\Daminion.Server.exe

Wait until it will be launched and close it

– Launch Daminion Server again from the admin panel

Q. We have recently received the attached error message while trying to access a server catalog in Daminion:

Error opening catalog. Time mismatch between Daminion Server PC and your PC! Server Time: … Client Time:…

A. The maximum time difference between Server and Client computers can be 10 mins. Please check also the timezone settings on the server and client PCs. They should match if computers are in the same office or home.
