installation - Can't install previously installed apps from Google Play

My Samsung Galaxy S2(I-9100) was upgraded to 2.3.6 by the technician at a Samsung Service Station. This resulted in a wiped-off of all the apps that I had installed along with some other data(like contacts,sms etc).

I had to go through the entire procedure of registering your phone with my gmail account.

I cannot install some of the apps that I had previously installed (from the web store) because I cannot choose the device and I get the message "Your device already has this app installed".

Any help would be appreciated.

Thanks.

The issue here is that the uninstall process wasn't registered at Google Play Store.

Without the uninstall process registered, Google Play Store still reports the app as installed on the device that's associated with your Google account.

To overcome this, you need to manually trigger the uninstall from the Google Play Store, within the "MY ANDROID APPS" list:

I have a couple of apps that I've uninstalled from my device and the uninstall process wasn't registered at Google Play Store. I'll use one as a guide:

1. 
   

   Access "MY ANDROID APPS" list, search for the desired app and click the recycle bin icon to trigger the uninstall:

   After confirming, the app will get marked as "removed":

   
   

   
   
   

   

   
   

   
   


3. 
   

   Now you can access the application at Google Play Store, and install it like you mentioned that you prefer to do:
