Hi @NikitaEgorov - can you post some more information please, the whole output of the command would be useful (you can obscure any secret details, it's just the flow of commands I'd like to see).

I have VM image Win2008r2Std-Gen1_boot.vhdx

execute this command PS C:\> ConvertTo-Dockerfile -ImagePath D:\Win2008r2Std-Gen1_boot.vhdx -Artifact IIS -Verbose -OutputPath d:\iis7

And get result

I catch it

Generate_IIS:165

if ($sourcePath -ne $mainVirtualDir.PhysicalPath) {
                    ProcessDirectory -DirectoryBuilder $DirectoryBuilder -CopyBuilder $CopyBuilder -SourcePath $sourcePath                  
                }

AclBuilder is null

hi @NikitaEgorov ,
did you find a solution for this issue?

[NikitaEgorov]

@andreputera
Yes!
See PR #55

[andreputera]

Thanks @NikitaEgorov

[andreputera]

I'm still having the same problems even after adding the "-AclBuilder $AclBuilder" at lines 165 and 192.

Update:
I close the powershell prompt and restarted Docker, now it works, no errors. Now trying to build it

[pulla2908]

I have a possible fix for this. I am creating a PR.
