Installing .NET 3.5 in Windows 10

May 26, 2023

One day I was asked to install .NET v3.5 on Windows 10 computer. The old application used there still required .NET 3.5.
The regular way to install brought me the 0x80240438 error, which means, that the file cannot be downloaded for some reason. Neither Windows features nor DISM worked. Well, I decided to download the offline version and install it. It failed with the same error simply because it was still checking something online. So, here’s the quick way to do it

  • Download the offline version from Microsoft website
    Download .NET Framework 3.5 SP1 | Free official downloads
  • Stop the Windows Update process. If you cannot stop it right now, restart the computer and then stop the process.
  • Install .NET v3.5. It still says “…downloading”, but go up to “…installing” this time.
  • Restart the computer again.

Done.

Here’s what to do if the mail queue of EXIM4 server is full

DELL Compellent Storage Capacity Planning with PowerShell

August 14, 2020

Capacity planning is a huge chapter in IT Operations. DELL SC API module for PowerShell makes it a bit shorter. I’d like to share some knowledge about three commandlets from this API: Get-DellScVolumeStorageUsage, Get-DellScVolumeStorageGrowth, and Get-DellScVolumeHistoricalStorageUsage. Using these commandlets across Storage Manager can save a lot of time on collecting the information.

May 5, 2020

Last year (in August if memory serves me well) Microsoft introduced a new signing for Windows updates. From that time all Windows updates are signed using SHA-2. The error 0x80092004 means that OS does not recognize a new signature.

Replacing the failed drive in QNAP

September 30, 2017

My QNAP storage got a failed drive (drive 1 to be specific). I pulled it out, inserted a new one and… nothing happened. On the web console it was showing RAID 5 Disk Volume with only drives 2, 3 and 4. The volume had “degraded” status and the Action button was greyed out. Here’s the solution:

Error 1605: The specified product key is not valid for the target edition

September 19, 2017

Unfortunately, Windows Server 2008 R2 Standard Edition has limitation of 32GB of RAM. Too bad, if more memory is needed. When I have run into this issue, I have decided to upgrade OS to Enterprise Edition. We have VLK license that supports both Editions, so I did not expect any issues with this.

Cannot copy files during in-place upgrade to Windows 2003

August 1, 2017

It’s hard to believe but I have recently needed to execute the in-place upgrade from Windows 2000 to Windows 2003. Nothing special, but in the middle of the copy process the installer threw out the error:

Setup Cannot Copy the File Cmprops.dl_

I could see the file on CD, but could not copy it. OK, I ignored the message and immediately got another one about the next file. Well, the setup was cancelled.

Robocopy Detects Files as Modified

July 18, 2017

From Windows 2008 to Windows 2012 the robocopy utility has been changed. Now it detects all files an “modified”.

I use robocopy to bring data from remote office to the centralized file server and back them up further. I’m not sure if robocopy actually copies files or just changes some attributes, but NetBackup sees the files as new and back up all of them even during incremental backup.

After battling the issue on my own I have opened a case with Microsoft. Together with MS engineer we have found two potential solutions
