Storefront cannot be upgraded because the following folders are in use

20 October, 2023

Hello Users,

I have noticed this error very frequently while upgrading storefront from 2203 LTSR CU2 to 2203 LTSR CU3 version.

Storefront cannot be upgraded because the following folders are in use by another program. Close the program and try again:

C:\inetpub\wwwroot\Citrix\apps\App_Data

undefined

Here is quite easy solution to handle this.

Answer:

1. Open Task Manager

2. Find the process Explorer.exe

3. Kill the process

4.  as explorer.exe is stopped, we would not be able to browse to the path through explorer

5. in Task manager -- Under File-- Run new Task

6. Enter the path for storefront binary -- Run the Installer.

7. Storefront installation should work fine now.

8. Post upgrade start the explorer.exe process from Task manager-- under file -- Run new Task

9. Reboot the machine and test the storefront application afterwards.

Everything should work fine :)

Thanks

Profile Settings are not saving in Citrix at second login

06 May, 2021

Hello Admin,

Here are some troubleshooting Tips for handling the profile Sync Issue. 

Problem Statements: Profile Setting is not saving at second login.

Technology used: Fslogix , Citrix UPM (multi Write back )and Citrix WEM

Way to troubleshoot.

1. Check the Fslogix Exclusions in redirection.xml for if any application folder is not synching

2. Check registry setting for HKLM\Polices\Citrix\user profile manager (ensure there is not inclusion or exclusions setting) only should have processed group setting and basic setting in user profile manager root.

3. reason could be if you used profile manager from WEM before deploying Fslogix and UPM for multi-Write back again so these old settings are not removed or overwritten after redeploying UPM.

4. once ensured all the above issues are fixed then try chnaging the setting and monitor.

it should work after making above listed changes.

Thanks

Admin
