Startdisk not recognized in installation

Hi all,

Currently I am trying to install the Sims 3 base game using all instructions I've been able to find. I've mounted both disks required ('The_Sims_3_Disk_1.ISO' and 'The_Sims_3_StartDisk.ISO'), however, when I double click them they simply open up the contents, nothing runs. I can bypass this by right clicking and selecting 'Install or run program from your media'. In the installation progress you again have to select these .ISO files in step seven (7. When, during Installation, the Istallation asks for Disk 1, click 'Browse' and select the StartDisk you have Mounted. (NOTE: In 'My Computer' or 'Computer' the StartDisk is called 'SIMS3')). When I select the mounted file, it again just opens up its contents. No file directory comes up, and I am unable to complete installation.

I've tried to look for other solutions on the forum and elsewhere, but to no success. Hopefully someone here knows the answer. Thank you in advance

Hello and welcome to the Forum @Sesquip,

Among the contents after you open up (the .iso image of "StartDisk"), you should be able to see some kind of setup.exe, autorun.exe, or something that start the installation.

If you can't seem to find out how to start the install, then there is another way: you can create an empty folder somewhere, and extract the contents of both .iso images, into that folder. 

Once you did that, try running the installation from that folder, and it should go.

Good luck, and keep us posted if you like!
