Summary0031297: TXmlRegistry writes numbers as cardinals but reads as signed integers
DescriptionTXmlRegistry.SetValueData uses IntToStr() from an unsigned integer to create the the string to write. This causes the system to promote it to IntToStr(QWORD). TXmlRegistry.GetValueData uses TryStrToInt() which then treats it as an unsigned 32 bit value. Any cardinal with the high bit set is, thusly, written to the XML file as an unsigned integer, but then read back in as a signed integer causing an overflow error.

They both need to be consistent.
Steps To ReproduceD := $FFFFFFFF;
TXmlRegistry.SetValueData('Anything', DTDWORD, D, sizeof(Cardinal));

Writes value as 4294967295

TXmlRegistry.GetValueData('Anything', DTDWORD, D, sizeof(Cardinal));

Returns an error.
