Random error during installation game created by Inno setup

Question

Hi when I use instalation that will install game it is OK. But sometime I will get this error:

C\\game\\ Scared2\\pad\\graphics02,zip An error occurred while trying to copy a file: the suource file is corrupted.

It can be different file. But always it is big file.

Here is my script:

[Setup]
InternalCompressLevel=ultra64
OutputDir=C:\SA

I know what is causing the problem,it's SolidCompression which is causing the problem.

How do I know that,because it already happened to me,and i solve this problem by reading some posts about DiskSpanning and compression in internet.

U can use script like this one to get best compression inside inno-setup.Just change the name and files etc.

#define MyAppName "My Program"
#define MyAppVersion "1.5"

You can modify the size of Setup-*.bin by changeing this

[Setup]: DiskSliceSize
Valid values:
 262144 through 2100000000, or max  
Default value:
 max (2100000000)  

Description:This specifies the maximum number of bytes per disk slice (SETUP-*.BIN file). Normally, this should be set to the total number of bytes available on the disk media divided by the value of the SlicesPerDisk [Setup] section directive, which defaults to 1.

This directive is ignored if disk spanning is not enabled using the DiskSpanning [Setup] section directive.

To optimally fill 4.7 GB recordable DVDs, use:

SlicesPerDisk=3
DiskSliceSize=1566000000

To optimally fill 8.5 GB (dual-layer) recordable DVDs, use:

SlicesPerDisk=5
DiskSliceSize=1708200000

To optimally fill 700 MB (80-minute) recordable CDs, use:

SlicesPerDisk=1
DiskSliceSize=736000000

To optimally fill 1.44MB floppy disks, use:

SlicesPerDisk=1
DiskSliceSize=1457664
