Install RemObjects Hydra - problems with Delphi 7

I have installed the beta version (RemObjects Hydra - on W10 64-bit

On opening Delphi 7 I get the following errors for IDE and Core.
So from here I had to do the following so that the above errors are fixed.

  • Create Dcu/D7 directory in C:\Program Files (x86)\RemObjects Software\Everwood…

  • Make it writable.

  • Open C:\Program Files (x86)\RemObjects Software\Everwood\Source\Delphi\ RemObjects_Everwood_D7.dpk

  • Compile

  • Create Dcu/D7 directory in C:\Program Files (x86)\RemObjects Software\Hydra for Delphi…

  • Make it writable.

  • Open C:\Program Files (x86)\RemObjects Software\Hydra for Delphi\Source\Hydra_Core_D7.dpk

  • Compile

  • Open C:\Program Files (x86)\RemObjects Software\Hydra for Delphi\Source \IDE\ Hydra_IDE_D7.dpk

  • Compile

Delphi will now start without error…
My questions are

  1. Should have the installation done the compiles?
  2. Have I done all the packages required?
  3. I found a BuildPackages_D7.bpg project but I was unable to compile the following packages in it.



Hmm, if the “Dcu/D7” folder did not exist — what folders were created? Are you sure Delphi 7 was checked in setup as installation target?

The folders that were created in …/Hydra for Delphi…

Yes i did a full installation

This is the only point in the installation that Delphi 7 can be selected.



Can you attach C:\Program Files\RemObjects Software\log.html for investigation, pls?

by default, only Hydra and Hydra_IDE packages are installed.
if installer detects Remoting SDK, it also installs Hydra_RO and Hydra_RO_IDE integration packages.

if you have installed Toolbar2000 or DexEv libraries, you can install Hydra_Dx/Hydra_TB2K integration packages manually.

Sorry there was no log.html file at that location.
FYI it was installed to …Program files (x86) …

All hidden items are set to viewable.

ah, yes, it should be in C:\Program Files (x86)\RemObjects Software folder

Sorry thats where i checked in the previous post.
No log file in C:\Program Files (x86)\RemObjects Software

I am trying it all again on fresh virtual machine to see if it was an Admin access problem.

after finishing Hydra installation, select Display package build log:
in this log everything should be green

All worked this time!!
I think it was down to admin rights on installation.
This time I got the following install page that had the compile check boxes -

Log file exists and is all green.

Apologies for wasting your time but thanks for your help.

Glad to hear that that sorted it, and our apologies for whatever might have caused the problem the first time around.

Hi due to other problems encountered with 64bit machines we are having to try Hydra 6 back on a 32bit windows 7 machine.
I am an administrator on this machine.
Delphi 7 has been found during the installation wizard

But when I get to the bpl paths wizard page the ‘Compile Unit’ options is not displayed and the so the installation does not create the required DCU’s

Have you any ideas what i can do please?


this can happen when you have broken Delphi 7 installation or some missing registry keys/values.
1st screen said that you have Delphi7 App key in registry
2nd screen said that installer can’t find bin\dcc32.exe and/or lib\rtl.dcp in the Delphi7 install folder.

can you drop to support@ some additional information:

  • screenshot of regedit.exe with values
    • HKEY_CURRENT_USER\Software\Borland\Delphi\7.0
    • HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Borland\Delphi\7.0 (x64 box) or HKEY_LOCAL_MACHINE\SOFTWARE\Borland\Delphi\7.0 (x86 box)
  • screenshot of ...\Delphi7\Bin folder with selected dcc32.exe
  • screenshot of ...\Delphi7\Lib folder with selected rtl.dcp

I have sent the screen shot to support email.
