Installing Creative Cloud-Error 205

DONT USE MICROSOFT EDGE when downloading Adobe CC Apps! It was giving me an error P205 and 201.  I switched the default browser to Chrome and it downloaded easily and right away.

Hello everyone. Today I  had the same problem but finally found a solution with the vpn changing. I am from Turkey and reconnected to USA service totally solved my problem. I used Tunnelbear but I do believe it doesn't matter which app or service you use. Hope that would help. Greetings...

My solution is Hotspot. I am connected mobile phone to my pc and downloaded CC app. It worked! But i couldnt download with lan or Wifi. I am still looking what is solution?

try rightclick on the setup file, click "Run as administrator".

It should solve the problem.

after hours of looking for answers I right clicked and ran as administrator and that worked for me.

I am on a fresh install of Windows 7 Ultimate 64 bit on a brand new hard drive. I have installed NO Antivirus, antimalware or any kind of security at all yet. I only only installed my video drives, my ethernet control, all windows updates, iE11 and Firefox and i continue to get 205 error. This is very annoying especially after reading so many people claiming this is a security software issue.

I need a solution that will work.

Here is the FIX... I had the same problem as so many of you. After 12 hours trying everything I could find online I ultimately got a online chat with a pretty sharp Adobe tech via chat. He connected to my screen and tried all kinds of stuff that did not work until he gave me some backdoor link to directly download PS, LR, and bridge, They are huge files and it took some time to DL, extract, and install but I have them all. He was on my PC for two hours so it was not a quick fix but it is fixed. I know it sounds crazy but it is actually some sort of network issue. So, don't spend hours trying to figure it out yourself. Get a chat or call Adobe for the direct download and hope to get someone as good as I did.

We use Cisco Cloud Web Security and it appears that files that are part of this installer might be getting blocked under malware, PUA, Corrupt files.

I had to reformat my hard drive, and when installing CC, I had the 205 error. Tried all the solutions: disabled McAffee; even tried uninstalling McAffee completely, put my desktop outside my router firewall, used the cleaner tool, a new user account, tried the root administrator account, nothing worked.  Adobe support spent 2 hours trying different things; zero help. Level 2 support failed also. They gave me a couple of things to try, useless.

So I gave up,  and installed Steam so at least I could play a game to get my mind off of this mess.  Steam installed fine, but the updated wouldn't finish.  Steam support told me (first try) that I needed to update my wireless driver.  I did, and presto, no problems.  I wondered if this was causing my 205 Adobe error also, and it turns out, it was.  The confusing bit is I installed lots of other applications, downloaded updates, all worked fine.  Apparently Steam uses the same validation techniques as Adobe, but unlike Adobe, their support actually knows what they are doing.  Apparently the root of the issue is something on Microsoft's end, so this problem could affect any brand of wireless. 

If you have the 205 error, try updating your wireless driver. 

I just find a way out to error 205 installing adobe CC.

In my case i tried to install it on my Standard Account permissions... even "open as administrator" didn't work, but I just make a new USER windows account with administration permissions, and it works !

Hopefully it helps.
