it looks like leftovers from one of your surprise "free trial" evaluation things that happened (without my consent) when I clicked a wrong item in a menu some moths ago?

[k1lb553cs]

The exact same thing is happening to me. I reinstalled my whole computer and even switched motherboards but it still keeps happening.

@OceanHydroAU @k1lb553cs Apologies for the late reply but if you are still facing this issue please do the following: 

• Close Fusion
• Go to Media Feature pack for Windows
• For the Windows version their machine is select the right media pack
• Install media pack
• Restart machine (not sure if this is needed but worth recommending)
• Launch Fusion

[frans_van_enschot]

hi Rajkumar, are jou sure that  Media feature pack for windows has something to do whit this error? have your thy this out by yourself? i have Windows 10 pro N version 22H2 what is not in the list. and this error came with an update from fusion 360 e few months ago.

Who has the same problem?

Thanks in advance

[RajkumarIlanchelian · Accepted solution]

@frans_van_enschot 22H2 is the last two in the list. Are you still having this issue ? 

[AndyDHarlow]

HI, Thanks for the solution 😀

I can confirm that I was having the same errors on start up but this has fixed the issue.

[frans_van_enschot]

Hi Reykumar,

It works.

Thank your very very very much.

Your the master.

Add media feature must don on my system on an other place.

Start->System-> add features

Thanks for your help

Lol. They edited my post and removed my word “cr4p” for “stuff” way to go. Silencing frustrated users.

we pay for your programs but they have so many bugs it’s insane.
