Unfortunately I don't get that "1.11.0 Some Reassembly Required" page . Let me illustrate the steps and results, just so you are clear
1. In my Account Info=> Your Orders => I see"Kerbal Space Program: Breaking Ground (Direct Download)" with a download button next to it.
2. Once I click the download button, it takes me to "Ready To Download page => in the page I see hyperlinks for the following:
- Breaking Ground Expansion 1.6.0. 1.5.1, etc
3. Just to be clear - I don't see the above "Kerbal Space Program: Some Reassembly Required" screen shot you provided above.
4. Now after clicking on the download (per my above #2), I get the exe installer. After clicking on the installer, it pops up the obvious windows popup "select destination location" where KSP_breaking_ground_expansion should be installed"
5. If I select the default destination and click next button, a setup box pops up stating "Looks like Kerbal Space Program its not installed in this folder....please choose the correct one." It does not permit me to install the program, as clearly I am missing some prerequisites.
I am not sure if I purchased the right program. Please help.
