Someone Please Help Me

Hello everyone, here's the situation:  I guess i'm a freakin moron for doing this, but I could use some guidance.  I've had Sonar 8.5.0PE for a couple of years and figured it was time update...I got all the updates, 1, 2, &3, tried to install them onto the audio PC, and it would not let me: 
 
 "Setup was unable to create the directory D:\Cakewalk Projects  Error 5: Access is Denied"
 
....I didn't know WTH that meant, and unable to change the file's destination, I resorted to Cakewalk tech support...one of the ways to fix this was:
 
"In some rare cases, XP users may encounter the same problem. You will need to give full permissions to your user account under HKEY_CLASSES_ROOT in the registry. Here are the steps:

1. Open the registry editor by going to Start/Run and typing in the following: regedit
2. Hit OK and right mouse click on HKEY_CLASSES_ROOT
3. Select Permissions
4. Under Group or user names, highlight "Users"
5. Under "Permissions" for Users, check the box for "Full Control"
6. Click [OK]
7. Reinstall Cakewalk"

Well, since I tried this and rebooted...My PC is not doing well at all, it takes about 10 minutes to do ANYTHING, and I mean anything, ie: start menu, right click properties...It actually runs Sonar fine, but not so much with windows...you can see my frustration, as I have projects that need to come off, like 3 hours ago...lol
 
This computer's pretty old, but still hold up very well, I only used 3% while recording a 3 hour live show, and it's only up to 13% after being mixed...but i can't do anything like this....Does anyone have any ideas how to to fix this
 
Windows XP Home, SP3
Pentium D 3.2Ghz DC
1G RAM
Echo Layla 3G PCI X 2

Glad I could be here to help.  P.S. I just a learned a ton by googling 'edison's cylindrical phonograph'.

Dave it's a rare one for sure It seems to be the first duo core Pentium processor following after the P4.  It should be all you need for live recording. I'm about to try my luck with a P4 and 1256 MB of RAM!  

FYI...   D: is probably your DVD or CD drive and you can't write to it like that.  


I posted it because of your answer.  It was like you were saying Pentium D was his Optical drive, that's all. You got my curiosity too as I had never heard of Pentium D so I looked it up. My DAW is a Pentium R which is also obscure. 


Actually I have recorded 14 tracks live of audio with no problem on vintage laptops, Last one was a Centron 1.7 MGz. Recording audio takes very little CPU power. Seems the OP is only recording Audio live as well. You transfer the projects into a more capable machine to handle VST's and Plug ins. 
My Centron died a year ago and I've been stealing my wife's nice  IBM Thinkpad to do on location stuff, she is not too happy about that. So computer tech friend of mine gave me this 2004 Toshiba Satillite  P4 a customer tossed out. It was free so nothing to loose. It must weigh 20 lbs! 

Ah ha, one need to go back to the first post, I see what you were pointing out now, damn all these letters and numbers. Yes for sure most computers D is the optical drive so the error would point to the software being confused about pathways.  

 My DAW however is unusually weird,  D is the C drive partition. The 2 DVD drives are F and H, The 2nd Data  HD is E and any external drive becomes G. 

There's not much info on the Pentium R series. My son built this computer from scratch. It does show 2 cores

The Pentium D apparently came out before there was even support for using the 2 cores. It's listed as in the P4 family. They hit a brick wall with clock speeds at 3.4(?)Mhz so I guess they thought up the 2 cores at slower speeds Idea. At 3.4 things began to get hot.
