FredS 138 Posted May 31, 2019 (edited) Using Berlin 10.1.2 I ran into two 'Access violations' while trying to generate a new hive: bds.exe -rNewHive Turns out this was due to the MidexExpert in HKLM: [HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Embarcadero\BDS\18.0\Experts] "MidexExpert"="d:\\Tools\\MMX\\14\\mmx_bds18.dll" To be honest that was actually still an MMX 13 entry even though 14 is installed. Perhaps it should have been removed? Deleting it made all work well, except no MMX.. Access violation at address 204F6A89 in module 'coreide240.bpl'. Read of address 0000003D. Access violation at address 205FC27A in module 'coreide240.bpl'. Read of address 00000000. Will fire off and email to: support@mmx-delphi.de Edited May 31, 2019 by FredS Fat Fingers Share this post Link to post
