The Sims 3 Seasons won't install - it says install Sims 3 first

[inkyplum]

I had to uninstall the Sims 3 and Seasons because it just randomly started getting really slow during game play (worked fine but one day just ended up slowing).

I’ve just reinstalled the Sims 3 and now I’m trying to install Seasons again, but it keeps telling me I need Sims 3 to be installed in order to install Seasons EVEN WHEN IT’S ALREADY INSTALLED. 

Does anyone have any idea as to what’s going on and how to fix it?

Are you trying to mix DVD and download version ?

If so, see if this helps you: http://sims3.crinrict.com/en/2013/09/dlc-compatibility-alert.html

Nope, two hard copies. They both installed perfectly beforehand, but after uninstalling I reinstalled Sims 3 perfectly - Seasons just doesn't think there's Sims 3 on there.

What's your operating system ?

[inkyplum]

Windows 8. Don't see why it should make a difference though, as they both installed perfectly before.

TS3 does not like to be reinstalled. Many times the game does not have to be re installed. Many times it's just the user data that's causing the problems. uninstall all. Use a registry cleaner like ccleaner form Piriform (there is a free version). Then install base game. Open Origin and make sure it is up to date. Open the game and patch. close game and open game again and there might be a store patch. Play game to live mode. NOW install the next pack, patch, etc.

I've already done this - twice. Hence, I came on here when it didn't work.

Operating system is important since troublesshooting steps may vary, especially if people have macs

• Anyways, does the base game work fine on it's own ? 
• Did you install to the default path ?
• What is your base game version right now ?
  
  Open the launcher and check the number in the lower left corner.

Base Game works perfectly. Yes and 1.57 etc

Did you install to the default path ?
