Running into an error while installing QuickBooks is frustrating especially when it shows a code like Error 1935 with no clear explanation. If you’ve seen this one pop up during installation, don’t worry. You’re not alone, and it’s usually not as complicated as it first seems. In most cases, QuickBooks Error 1935 shows up when the system is trying to install or update .NET Framework, which QuickBooks needs in order to function properly. If that process gets interrupted or blocked, the whole installation fails.
Through this blog we will walk you over everything you need to know about fixing Error 1935 so you can get back to running your business without more delays.

What Is QuickBooks Error 1935?
This error typically shows up during installation (or reinstallation) of QuickBooks Desktop. You’ll see a message that reads:
“Error 1935: An error occurred during the installation of assembly component…” QuickBooks tried to install something behind the scenes usually a Microsoft .NET Framework component but it didn’t work.
What Causes Error 1935?
Let’s look at the most common reasons behind this installation error:
- .NET Framework is damaged or not installed properly
- An antivirus or security program is blocking the installation
- Windows updates are missing or incomplete
- Another installation is already running in the background
- System files are corrupt or registry issues exist
The good news is that most of these issues are fixable with a few simple steps.
Step-by-Step: How to Fix QuickBooks Error 1935
Let’s work through some effective solutions. Start from the top and work your way down there’s no need to try everything at once.
Step 1: Restart Your Computer
Sounds simple, but a restart clears out many temporary glitches. If any installation processes were stuck in the background, this gives them a fresh start.
After restarting, try the installation again.
Step 2: Turn Off Antivirus Temporarily
Security software can sometimes block installations it mistakenly sees as threats.
To test this:
- Temporarily disable your antivirus program (each brand has a slightly different method)
- Re-attempt the QuickBooks install
- Once installation is complete, turn your antivirus protection back on immediately
Don’t forget to reactivate it afterward. You don’t want to leave your system unprotected.
