Application Installation error 1324 The path C: contains an invalid character


Recommended Posts


My Kaspersky internet securty subscrition expired i paid for 3 years in 2015,

i had issues with renewing so it wouldn’t allow me, idk why, and there is no option, button anywhere on the program to renew.

I ended up rebuying the Kaspersky Internet Security, i downloaded the package via email reciept and then begin to install, the progress bar on the installation would get halfway and then stop and an error box would popup it says:

Application Installation error 1324 The path C:  contains an invalid character

never had this issue before, never had to reinstall before, as i was able to renew back in 2015, now idk what the issue is.

 heres screenshot of the error:

I just did a full computer scan with Kaspersky, took about an hour and my computer is clean. Is there a way i can just renew trough the program, instead of having to reinstall?


My computer specs are

  • Win 10x64 bit
  • Intel I7-700K
  • Nvidia GTX 1080
  • Ram is 32gb @ 3600mhz
  • PSU - Evga 1000watt
  • OS is on an SSD


How do i fix this?

Hello @Julian, Welcome.

It is possible that something is wrong with the environment variables.

Please open a CMD window and run the command 'set'. The variables will be displayed.
Check 'TEMP' and 'TMP'. Do they show a valid path?

Ok i figured it out the CMD, apparently i was putting in ‘set’ as you have it,

anyways this is what i have, does it look correct?

Also after that initial screenshot on my OP, it said i may have a virus, so i downloadd the KRT tool from the website, did a scan and it found 2 adware objects, and i removed them, i will try to run the installation for the internet security again and see if anything changes and then post a reply with my results.

Another user account?

Like on the website here?

Idk if a new account would make any difference i mean if the installer is installing into a specific path, or folder, wouldn’t the same installation attempt basically do the same thing?

   Also idk how that would work, having a new account while having a license linked to a specific account, would probably deny me access, or rights to use, cant say.

     So your suggesting to create a new account on the website and then just reinstalling the exe i have, or what did you have in mind?

I have a startup.exe  and kis21.2.16.590en_es_25815.exe i got from my email confirmation, both do the same exact thing, and i get the same exact error.

Ok i setup another user, downloaded the start.exe as i had on the other user, ran it

and got the same error.

I was looking at these two paths

TEMP=C:\Users\Gunter Severloh\AppData\Local\Temp
TMP=C:\Users\Gunter Severloh\AppData\Local\Temp


and there is no TMP path unless im blind i dont see it.

What else can we do?

Hi guys, sorry for not responding, i gave up on this back when i was working on it, and decided to let the subscription expire, so it did and i just tried the activation code again and it worked, so no issues, program is running like it should and everything is updated and working fine.

   So for those with possible similar issue just let it expire and then either renew or enter an

activation code.

Thanks anyways for the help, sorry for the lack of response before.
