PS script for blog: Enumeration of the files failed

I keep getting the following error from PoSh1

Unexpected token ' ' in expression or statement.

At C:\Users\JES\Desktop\GetInvalidImagePathsV2.ps1:89 char:50

+                "    Service Name    : $Name`n" `  <<<<

Same issue as above.  Maybe an issue of cut and paste?  Any idea how to fix?

The errors you report might be caused by invalid line breaks after copying the code from the web site. The code lines have several line breaks just for readability, so it's safe to delete those.

I found that the following correction worked for me (one single line):

Write-Host "$Header`n     Service Name    : $Name`n    Service Caption : $Caption`n    Registry key    : HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\$Name\ImagePath`n    Value           : $Path`n    Reason          : $Info`n `n" -ForeGroundColor "$Color"

Insert this as new line 88 and then delete the original code block.

Yes, Nils is correct, just use a script editor to remove invalid line breaks.. Thanks for script Tom

Thank you so much for the script...it saved my life...ok, it really just saved my forehead since I was banging it agains the wall trying to locate the problem service.

THANK YOU!!!!! :O)

Thanks for this info.  I am not sure what to do to remove the line breaks.  Can someone point me in the right direction or provide the script without the line breaks please?

Thanks!!

After replacing line 88 and deleting the block I get the following. I do not use powershell alot but would like to see if this can identify my VSS issue. Thanks for any help.

Missing closing '}' in statement block.
