Installing Dimension PRO happens that all the install sequence goes until the end, but then any .exe or dll is present in no location.
Tried:
1) clean Install
2) install from file or CW center
3) cleaned Windows register
4) tried two different serial Numbers.
5) always no antivirus or antispam active
Any idea?

little more info:
you mean you have looked for it in your program files directory / VST plugins ?
 
or you mean your not seeing it in the plug in menu ?
if that's the case, reset/rescan your plug ins.

I mean that after the installation NO DimensionPro exe or dll are present. Installation procedure ends with no problems. But the dimension Pro ( 32 or 64) exe or dll files are not present into the desidered folders. They are not present at all and anywhere.
I really can't understand why!!!

have you set your Windows Folder options to "Show hidden folders" ?
not sure if that would be the case but my suggestion is to re install it and this time take note of the directory they are going to (is this the default directory ? (Program files/cakewalk/VST plugins) ?
default installation or are you storing these somewhere else ?
 
also remember to install D Pro as administrator.
Right click/Run as administrator.

search on: 
 
x64.dll
x64.exe
 
see what shows up

Jus to be clear. Dimension .exe files are not placed in the "C:\Program Files\Cakewalk\Dimension Pro" folder.
They are in the "C:\Program Files\Cakewalk\Vstplugins\Dimension Pro" folder.
 
Goofy, if you ask me.

Thank you everybody. Sorry if I can't explain very well. The .exe or .dll files simply are invisible. They are not in any of the well known location, that you suggested to check. I'm a long time (cw6) happy user of CW daws and I know these very well .
I only see that in the list of programs is possible to uninstall Dimension Pro, even if it's not actually present.
This seems to me like an Antivirus behavior but during the installation Karpersky was always switched off. Moreover, to avoid any problem, in the list of scanning exclusions I included D-pro installer.

I recall a similar report quite a while ago but do not believe the user posted their resolution.
 
If you have an older version of SONAR with DPro bundled, try using that installer. DPro was always bundled as a separate disk or set of downloadable installers. DPro has not changed in years but the installer has. The most recent version of DPro is v1.5. If you have to go back to a very old version of SONAR, grab the update(s) to v1.5 here:
v1.2 update http://www.cakewalk.com/Support/Knowledge-Base/2005302/Dimension-Pro-1-2-update
v1.5 update (requires v1.2) http://www.cakewalk.com/Support/Knowledge-Base/2007013166/Dimension-Pro-Dimension-LE-1-5-Update
 
The expansion packs which are included in the Command Center installers are also available at the knowledge base http://www.cakewalk.com/Support/Knowledge-Base/2007013208/Free-Dimension-Pro-Expansion-Packs-1-3
 
 
BTW, if there are multiple serial numbers in your account use one beginning with CWDM150 with v1.5 or CWDM110 for v1.1

default installation or are you installing to somewhere else ?

Already tried both the online than the offline installation with same result.
Btw I'm going to try from DVD (sonar X1) and then eventually upgrade. I really didn't think to this possibility.
Thanx.
I'll inform you.
