I ran into these situations trying to load a mega mod game.
Heart of the Wood
If you open up the RAR file, you see the "HeartWood" folder and the file "Setup-HeartWood.tp2". I also expected to also see a file "Setup-HeartWood.exe". Since it is not there, you cannot install the mod.
Munchmodv26_Weidu
When you open the RAR file, you see only the "Munchmod V2.6 Weidu" folder. Inside the "Munchmod V2.6 Weidu" folder are the "Munchmod" folder and the files "setup-munchmod.exe" and "setup-munchmod.tp2". You need to copy the "Munchmod" folder and the files "setup-munchmod.exe" and "setup-munchmod.tp2" to the "BGII-SOA" folder to load the game.
Bag Bonus
It is the same as Munchmod.
tbquest_v2.02
You get an error message because the file "tb#quest\setup-quest.bat" cannot be found. It is there as "tb#quest/setup-tb#quest.bat". If you click on the file "BGII-SOA/setup-tb#quest.exe" it will load. Or you can change the name in th archive to "tb#quest\setup-quest.bat". I have not tried changing the name to see if that works too.
Deeper Shadows of Amn
You get an error message that it cannot find the file "DSoA\Readme". The file is named "DSoA\Readme for Deeper Shadows.txt".
I hope this information helps.
