Inventor cannot access your license?

[Anonymous]

Good day!

I've been using Autodesk Inventor Pro 2021 with education license for a little while now. But suddenly i get a prompt saying "Inventor cannot access your license" whenever i start inventor. How can i resolve this? I've searched in the net for solutions but i think it is better to just ask it here. I attach a screenshot of the error below.

Thank you!

Hi, 

Are you done reinstalling it?  Did it work? The customer support advised me the same solution.  But im hesitant on uninstalling my inventor.

Hello @Anonymous  & @cetin_yildirim, 

Depending on your license type & current environment the solutions will be different, the error message indicates the possible solutions based on license type. 

What license type do you have? Are you working remotely, via VPN etc.? 

Network License Type 

It is recommended that multi-user subscribers Borrow a License or Request an at home use license to avoid issues accessing a remote license. Make sure your products are eligible for a home use license by reviewing the eligibility requirements.

Single User License Type

1. The latest Autodesk Licensing Service update needs to be applied, after applying the update make sure the service is running. 
2. Make sure you have an uninterrupted high-speed connection to the internet & try adjusting your LAN  & proxy settings etc. or try a different wifi network
3. Review your Autodesk Account make sure the user is assigned to the application, signing in with the proper Autodesk ID & Password, resetting and Changing Your Autodesk Account Password
4. Temporarily disable security settings like Antivirus, Firewall & UAC on your Windows operating system
5. Adjust the systems clock settings
6. Whitelist the sites listed in these articles:

• What URLs/Protocols Are Accessible for Subscription Licenses
• Subscription Licensing Error: "Establish an Internet connection to continue"

Hello,

we cleaned uninstall after Install lmtools and Inv 2021 also ACAD 2021  then both of them working.

There is no problem.

but this should be last way to solve this case.

hello @natasha.l 

You  r right  but  my license is NFR and I don't use any server pc, client and server machine  are same pc so I  dont't need to use borrow license or VPN.

When I have install first time Inv 2021 I met same problem also I  get license error message from ACAD (

"License Error - ADLSDK_STATUS_AUTH_PENDING 22:Retry limit exceeded connecting to the Service" when launching AutoCAD or AutoCAD LT 2021 | AutoCAD 2021 | Autodesk Knowledge Network

https://knowledge.autodesk.com/support/autocad/troubleshooting/caas/sfdcarticles/sfdcarticles/Licens...

)

I have used this solution for  ACAD error and after this my Inventor license  problem solved (kill two birds with one stone)

 the problem has repeated for Inventor but ACAD error message changed and I couldn't solved this time so  I had to  clean uninstall.

@Anonymous  you can try this  https://knowledge.autodesk.com/support/autocad/troubleshooting/caas/sfdcarticles/sfdcarticles/Licens...

Hi @natasha.l ,

Im using a single user, educational license of Autodesk Inventor Pro 2021. Ive done updating the licensing service as instructed in the link

https://knowledge.autodesk.com/search-result/caas/downloads/content/march-2020-autodesk-licensing-se...

but i still have the same error. I may be wrong, but i recall that my license activation was automatic when i installed inventor. I didnt have license manager, but i was still able to use inventor before without any error. 

Should i have a license manager (LMtools) even if my license is single sign on license type? 

[natasha.l]

Hello @Anonymous, 

You don't need LMtools or anything like that, because your license is managed & validated by online services. 

Please run through all the steps I provided above for Single User because your license uses this technology.

Hi @natasha.l , 

Thank you! I resolved it now. I just discovered that Autodesk Licensing Service is disabled on startup in my windows services setting. The error has nothing to do with the license at all. Thank you for the help!

Hello @Anonymous, 

Thank you for returning. I am very glad you resolved this & I wanted to explain how this licensing service operates. 😊

When starting an Autodesk application, the Autodesk Licensing Service validates your license by accessing the Autodesk server & verifying your username. When this service is not running it will cause all Autodesk products that utilize this licensing to stop working.

Users of Autodesk software will need to maintain this service in good standing by applying the necessary updates & verify that the service is running so a license can be validated on start up.

Updating the "Autodesk Licensing Service" worked

This solved my issue. I tried a clean install and changed my password. But to no avail, after reading this post I checked Windows services and sure enough, it was disabled, I think as a result of my helpful antivirus software tune-up feature.

Go to the Windows Search bar, type “Services”, select “System Services” and scroll down to find “Adsk Licensing Service”, In the dropdown menu select start-up type “Automatic”.
