Yes. FYI, you can run that copy of TS2010 in-place from your D: if you want to, and spare yourself the hassle of copying everything over. But, assuming you want to reinstall so everything's all proper, you can:
1. Copy the old installation over top of the new one on your C: drive. (I suggest only patching the new installation to the same level as your old copy; you can patch further after you copy everything over.)
2. Copy just the userdata folder from your old installation over your new one (probably the least desirable of all choices.)
3. Use CMP's Import Content feature to import the contents of the old Userdata folder.
4. Run the old installation's CMP, export all desired content to one or more CDP files, then reimport it via the new installation's CMP.
You may get varying opinions as to which method is truly best but #1 works for me and happens to be the fastest, along with method #2, will retain any keyboard map changes and screenshots.
