For one of the ISM projects, we have an INSTALLDIR configuration which defines the destination directories which causes a problem to generate a Patch. the particularity of this configuration is that we have directories of the same identical names in two main directories. For the directories of the same names which contain subdirectories but which do not contain files, we have this problem. When we put files in these directories in our sources , we were able to generate the patch which confirms the hypothesis that this particular structure is the cause of this problem. On the other hand, i puted the same MSI in previous and latest folder in Disk1. I compared both MSI with WiDiffDB.vbs tool and the result is 'Database identical'. Then i performed the build without any changes and i get these entries 'DIRECTORY DELETE' and 'DIRECTORY INSERT' after comparing the second time between the previous MSI and the latest MSI : Directory DELETE [_5047FEC7BF13463F802A909ECD770F13] Directory Directory_Parent [_2A79C276BD2D4B24AC20ED697191960E] {_5047FEC7BF13463F802A909ECD770F13}->{_0807EA1407C641B0A3507E2FFCC091CC} Directory DELETE [_7011E91E281946099BECBF404B5233AA] Directory DELETE [_ED728CE029EA4F65942225F3727584A2] Directory Directory_Parent [_6D49603ED3F94663B85F40C0DD54A18B] {_ED728CE029EA4F65942225F3727584A2}->{_7F660A07FB4E4C66B1BAB38F500D38EC} Directory Directory_Parent [_2E527A65A5D84BEBB8972A2788974806] {_ED728CE029EA4F65942225F3727584A2}->{_7F660A07FB4E4C66B1BAB38F500D38EC} Directory DELETE [_C2222D9F7F764B12B15CD4AD0B326304] Directory DefaultDir [_4352EBE7A3CB4A1FB990876CFBF52578] {}->{theme} Directory Directory_Parent [_4352EBE7A3CB4A1FB990876CFBF52578] {}->{_36ACAEC335AE4EA3BB87C0D55E903965} Directory INSERT [_4352EBE7A3CB4A1FB990876CFBF52578] Directory DefaultDir [_24C3DF8BD99B491B94975BD27CE51DB6] {}->{theme} Directory Directory_Parent [_24C3DF8BD99B491B94975BD27CE51DB6] {}->{_9C9468CF34D64A459DF79B7E347E8A7D} Directory INSERT [_24C3DF8BD99B491B94975BD27CE51DB6]
When i puted two files in both folders 'theme' these entries were no longer exists in MSI comparaison. and i'm able to generate a patch in this case.
There is any solution for this issue ? I'm using InstallShield 2018.
