Little trouble with Mod install

[WOODY01]

I have two copies of the game on my computer. One in the Steam folder and another outside of the Steam folder. Both are updated to 1.0. I deleted the .90 version not in the steam folder before copying the 1.0 version. I tried installing Engineer then Mechjeb on the copy and both did not show up in the game except Mechjeb's part which did nothing but use power. I assumed it was because of the mods having issues after the update but noticed other people mentioning they were using them.

I then tried adding the mods to the copy in the Steam folder and both worked.

Decided I must have made an error somewhere, pretty sure I have, and deleted the copy not in the Steam folder and copied it again. Installed Engineer on that copy and it did not work.

I have installed and tried a lot of mods for KSP both adding them to the copy in the steam folder and the copy not in the Steam folder with no problems.

What obvious thing am I missing here?

Moved to modded support, where the right people are more likely to see it.

I'm having the exact same problem with a non-steam install. Parts show up, but no icons in the toolbar, and the plugins do essentially nothing. Any ideas? Installed the same way as usual, never had a problem before.

I am having the same problem on the non-steam install with v1.0, I recently have tried installing just a few mods onto 1.0 after missing the features they provided: AlarmClock, Kerbal Engineer, and Transfer Window Planner.

I'm pretty sure the mods are correctly copied in the GameData folder, and I can even see the KSP startup thing show that it is parsing those directories, but the mods do not appear to load. Confirmed that I have the mod versions released for 1.0.

Last time I installed mods was 0.25. Worked perfectly then.

Just FYI for the other people having this problem, after rebooting the computer a few times, the game eventually accepted the mod installs. Best I can figure my anti-virus was somehow interfering with the game recognizing the new files.
