Markaad ku rakiban tahay .NET Framework kombiyuutarkaaga, haddii aad hesho  The timestamp signature and/or certificate could not be verified or is malformed  khalad khaldan yahay, waxaad eegi kartaa xalalkan si aad dhibaatadan meesha uga saarto. Waxa kale oo laga yaabaa inay dhacdo marka la furayo ama la cusboonaysiinayo qaar ka mid ah apps-ka dhinac saddexaad ee kombuyuutarkaaga. Si kastaba ha noqotee, waxaad raaci kartaa talooyinkan iyo tabahan si aad meesha uga saarto arrinta.

Iyada oo ku xidhan halka ay dhibaatadan ka timid, fariinta khaladku waxa ay tidhaahdaa sidan:

Installation Did Not Succeed

.NET Framework 4.8 has not been installed because:

The timestamp signature and/or certificate could not be verified or is malformed.

For more information about this problem, see the log file.

Waxa kale oo laga yaabaa inaad hesho koodka khaladka ah 0x80096005 markaad ku rakibayso .NET Framework kumbuyuutarkaaga.

Sababta koowaad ee dhibaatadan waa rakibaha duugoobay, darawalka, ama shahaadada xididka. Darawal kasta oo aad rabto inaad ku rakibto kumbuyuutarkaaga wuxuu u baahan yahay in si dhijitaal ah loogu saxiixo. Si kastaba ha noqotee, haddii ay duugowday, waxaa laga yaabaa inaad dhibka ku qabato kumbuyuutarkaaga.

Waa maxay shahaado khaldan?

Shahaadada khaldan waa shahaado khaldan oo lagu duray Qaabdhismeedka NET ama darawalka ama software. Marka ay Windows xaqiijin kari weydo shahaado ka hor inta aan la rakibin abka sabab kastaba ha noqotee, waxay calaamadisay shahaadada inay tahay shahaado khaldan.

Sidee loo hagaajiyaa Saxeexa^(Signature) wakhtiga iyo/ama shahaadada lama xaqiijin karo ama wuu khaldan yahay?

Si loo hagaajiyo saxeexa wakhtiga iyo/ama shahaadada lama xaqiijin karo ama khalad khaldan yahay, waxaad u baahan tahay inaad hubiso ansaxnimada shahaadada, oo ka soo dejiso rakibihii ugu dambeeyay website-ka rasmiga ah. Marka laga reebo taas, waxaad sidoo kale joojin kartaa xaqiijinta saxeexa koodka.

While installing a .NET Framework on yоur computer, if you gеt The timestamp signature and/or certificate could not be verified or is malformed error, you can check out these solutions to get rid of this problem. It may also happen while opening or updating some third-party apps on your computer. Either way, you can follow these tips and tricks to eliminate the issue.

Depending upon the source of this problem, the error message says something like this:

Installation Did Not Succeed

.NET Framework 4.8 has not been installed because:

The timestamp signature and/or certificate could not be verified or is malformed.

For more information about this problem, see the log file.

You might also receive an error code 0x80096005 while installing the .NET Framework on your computer.

The primary reason for this problem is the outdated installer, driver, or root certificate. Every driver you want to install on your computer needs to be digitally signed. However, if it is outdated, you might get the problem on your computer.

What is a malformed certificate?

A malformed certificate is a faulty certificate injected into a .NET Framework or driver or software. When Windows cannot verify a certificate before installing the app due to any reason, it tagged the certificate as a malformed certificate.

How do you fix The timestamp Signature and/or certificate could not be verified or is malformed?

To fix The timestamp signature and/or certificate could not be verified or is malformed error, you need to check the certificate’s validity, and download the latest installer from the official website. Apart from that, you can disable the code signing verification as well.

The timestamp signature and/or certificate could not be verified or is malformed

To fix The timestamp signature and/or certificate could not be verified or is malformed error on Windows 11/10, follow these steps:

1. Check the certificate timestamp
2. Download the latest installer
3. Unblock driver
4. Disable code signing for the driver package
5. Disable driver signature enforcement

To learn more about these solutions, continue reading.

1] Check the certificate timestamp

It is the first thing you need to check before heading to other steps. If the certificate is expired, you cannot install the driver or the .NET Framework on your computer. To do that, follow these steps:

• Right-click on the file and select Properties.
• Switch to the Digital Signatures tab.
• Select the signer and click the Details button.
• Click the View Certificate button.
• Check the Valid from date.

If it is not expired, you can follow the rest of the workarounds. However, if it is expired, you can contact the driver developer or download the latest version of the installer.

2] Download the latest installer

Whether you are getting this issue while installing .NET Framework or anything else, you can download the latest installer from the official website. For .NET Framework, you need to head to the dotnet.microsoft.com website and select the version you want to download. If you downloaded the installer a long time ago, it is better to follow this solution.

3] Unblock driver

You might sometimes see this error while installing the driver or .NET Framework right after downloading it on your computer. To get rid of that, you need to unblock the file. For that, you can right-click on the downloaded file, tick the Unblock checkbox in the General tab, and click the OK button.

Next, you can continue with the installation process.

4] Disable code signing for driver package

This Group Policy setting lets you install a driver that doesn’t have a digital signature. You can follow this guide when the timestamp is expired as well. For that, do the following:

• Press Win+R to open the Run dialog.
• Type gpedit.msc and press the Enter button.
• Go to User Configuration > Administrative Templates > System > Driver Installation.
• Double-click on the Code signing for driver packages setting.
• Select the Enabled option.
• Choose the Ignore option from the drop-down list.
• Click the OK button.

After that, close all the windows and check if you can install the framework or not.

5] Disable driver signature enforcement

You can completely disable driver signature enforcement on your Windows 11/10 computer to fix this problem. It doesn’t consume much time and fixes the issue immediately. Therefore, follow this detailed guide to turn off driver signature enforcement on Windows 11/10.

That’s all! Hope this guide helped you fix the issue.
