Just incase anyone else has this issue (missing msvcr71.dll)
1. Download this: http://download.dll-files.com/ca2f560921b7b8be1cf555a5a18d54c3/msvcr71.zip?0XMmSDXMjS
2. Unzip and place contents at these locations (i put it in all the places i saw people mention through various topics online, im not sure which did the trick but you can do a process of elimination if you desire )
- C:\Windows\SysWOW64 (only if your on 64bit)
- C:\Program Files (x86)\Steam\SteamApps\common\Sins of a Solar Empire Rebellion
- C:\Program Files (x86)\Steam\SteamApps\common\Sins of a Solar Empire Rebellion\ConvertXSI
3. Restart computer
4. Praise the forumites here for the help & super swift response times!!
